What would the formula be to calculate the number of combinations of six out of 12 total numbers?
 

Excel Facts

Select all contiguous cells
Pressing Ctrl+* (asterisk) will select the "current region" - all contiguous cells in all directions.
Oh, that was easy. I'm embarrassed! Thanks!

Now the hard part: What calculation can determine what those combinations are?

Thanks a bunch!

Ha, ha. Wow! That is some VBA code! Far over my head. I get a compiler error on thi line:

= True Or BufferPtr = UBound(Buffer()) Then......

I can handle some basic VBA, but I don't have a clue about this one.

Well, I expedited an long planned project. The page, in a not-quite-finished state is
Powerset, Subset, and Combinations & Permutations

To use UDFSubset as an XL function, enter the elements of your set (the 12 numbers) in a column. Enter the number of selections you want (6) in some other cell. Then, select COMBIN(12,6) cells in a column and *array enter* =UDFSubset({range with 12 numbers},{cell with # to select},",")
