Casual Googling resulted in pretty disappointing information: many suggested to generate a bunch of random integers in [1, N], possibly with repeats, until you cover all N integers. Then, pick the previously unseen unique numbers to extract a subsequence. But you can actually do this with N random numbers. This completes the proof. For each row, we swap the k-th Column A and m-th Column B numbers in the previous row.
This is what the gigantic IF statement is doing. Finally, we drag and expand the formula to populate the rest of the cells. I personally find this step most satisfying when I program in Excel.
This step is very easy in Excel. We just keep populating Column A through G for subsequent rows. The only thing to watch out for is Column A should repeat 1,2,3,4,1,2,3,4…This can be achieved by using relative reference. When everything is said and done, here is the distribution of 5!

Here is what the formula looks like: For each row, we swap the k-th Column A and m-th Column B numbers in the previous row. C5:G5 is the random permutation. Most pertinent to the reader: we are looking for a data scientist to help our customers discover more value from their data.

Returns the number of permutations for a given number of objects that can be selected from number objects. A permutation is any set or subset of objects or events where internal order is significant.
Permutations are different from combinations, for which the internal order is not significant. Use this function for lottery-style probability calculations. An integer that describes the number of objects.
An integer that describes the number of objects in each permutation. Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter.

In the first scenario, there are N identical dice, each with M sides, with each side uniquely labeled from 0 to M So, a 6 sided dice would have the numbers 0 to 5 and a tetrahedral four sided die would have the numbers 0 to 3. In the second scenario, each of the N die has a different number of sides. This scenario might apply to, say, all the possible permutations that one can get from a car model with M trims, N tire choices, P interiors, and Q colors.
The idea here is to have one die correspond to one column. Each row will have one possible permutation, starting with zero. So, for a six-sided dice, we will get 0, 1, 2, 3, 4, 5, 0. The next column over will use a slightly modified formula. It will retain the current value until the previous column rolls over to zero. When that happens, the column will use the same MOD formula to calculate its next number. So, it will go 0, 0, 0, 0, 0, 0, 1. Each of the however many columns we add will use the same approach, making this solution easily scalable.
Since each row holds one permutation, the total number of rows required will be M N. With this background, we can implement the solution in Excel. The number of dice positions is in B3, the number of sides on each die the range of values for each position is in B4.
Column C sequentially numbers each permutation. E3 is copied over to F3:M3. E4 is copied over to F4:M4. C4:M4 are copied down until column C lists the final permutation i. One can also make sure that at least one row contains all blanks.
With the above solution, it is relatively easy to figure out how to get all the permutations for the scenario where each die has a possibly different number of sides. Instead of the divisor of the MOD operation being the same number B4 in the above examplewe use a different divisor for each die. The rest of the solution remains the same!
Row 2 lists the number of choices possible for each column. In the above example, they range from 9 in position 1 column C to 2 in position 8 column J. The total number of permutations is given by the product of all the individual ranges. The sequential numbering of the permutations is in column B. Copy D4 to E4:L4. Finally, copy B4:L4 as far down as necessary to get the permutation numbered the same as the value in A3. Alternatively, ensure that at least one row contains all blanks.

Its called a Cartesian Product or a Cartesian Join. See the image below for our two tables. Both of these have been defined using the Format as Table icon on the Home ribbon see this article to learn more about Format as Table. To achieve this we will create two simple queries, one for each of our tables.
Then a third query will merge the two queries to create the combinations in a new table. This opens the Power Query window. Click the Add Column tab and click the Custom Column icon. This opens the Add Custom Column dialog. This will add a new column to the table with 1 in each of the rows.
In the dialog that opens choose Only Create Connection and click Load. Repeat steps 1 to 6 for the Department table and it should look like the image below. On the right of screen double click one of the Queries. If the Queries are not visible on the right then click the Data ribbon tab click Show Queries. Click the arrow on the left of the table to display both queries. Right click the tblStates Query on the left and choose Reference.
This create a third query that we will use to merge the two tables together. This opens the Merge dialog. In the top table click the ID column. In the drop down below select the tblDepts Query and when that displays click the ID column in that as well. Click OK. We have the tblStates Query with a new column. To see the final table click the opposing arrows in the header of NewColumn.
The table is created but it still has the ID column which you can delete by selecting it and clicking the Remove Columns icon. This takes a lot longer to explain than it does to create. Blank file.

What is the formula? I'm having a hard time figuring it out!! Desperately, Jenny. Hello gurus! Here's my question I have a list of numbers and I want to know how many combinations and what they are of adding the numbers will equal an amount.
I want to know which numbers i. AND, if possible, colorcode the cells added for each combination. Good luck and thanks!! I want to generate all possible combinations of 11 combination 4.
I know there are possible combinations but how can i let excel generate all the combinations. For example. Is there a worksheet function that will generate all possible combinations of a set of given numjbers.
For example, 1, 3 and 8 would generate,and so on I want to create 6 numbers from 11 numbers. But i dont want duplicate series. I mean 1,2,3,4,5,6 and 6,5,4,3,2,1 are duplicates. Football soccer Predictions Formula - Excel.

In excel, we use permutations more often than we realize. However, the reason I actually looked into permutation, was for a quirky solution to automating a complex filter problem.
As you may already know, advanced-filters has this amazing feature called criteria range. The criteria specified in a row are combined using the AND operator, and then the rows are joined using the OR operator. Unfortunately, I needed it to work the other way around: OR operator within the column and the AND operator between columns.
I needed to filter out a subset of products, sold at a subset of states, delivered to subset of localities. The first idea I got was to write a task specific macro to repeatedly add criteria to a filter, and later copy paste visible cells to another sheet. Where is the fun in that? So, I thought of something different. I suspect this will wildly increase the time excel takes to execute the filter, but hey mixing and matching is fun!
Most of them involved a bunch of for-loops specific to the number of lists in question; there was this one with a convoluted formula that works for two lists only; and finally, there was one with a sql-based-cartesian-product, which I did not quite understand. The solution I came up with is little unconventional, but very intuitive. Say we have three sets:. For instance, in the second column, each element features twice, and that entire pattern marked by the blue boxes repeats twice.
The size of a pattern blue box is equal to the product of number of elements in the list and the number of times each element repeats itself red box. The number of times the pattern repeats itself in each column is obtained by dividing the number of permutation possible by pattern size.
Now we calculate, number of permutations possible number of rows by multiplying the number of elements in each list together. Then we calculate how many times each element repeats in a pattern, and how many times the patterns repeats itself for each of the columns. Finally, run a bunch of for loops to populate an array with the results. I coded a generic sub so you could use it in your projects, for advanced filters, and get all permutations in general:. I also wrote a simple cover procedure to illustrate how the above macro could be used.
Download the workbook to check it out. You could perhaps consider designing a tiny userform instead of this cover macro, for your add-in.
