Combinations
Following is a macro based solution form Myrna Larson (Microsoft MVP) on
permutation and combinations 1. It allows Combinations or Permutations (see note below). 2. The macro handles numbers, text strings, words (e.g. names of people) or symbols. 3. The combinations are written to a new sheet. 4. Results are returned almost instantaneously. Setup: In sheet1: Cell A1, put “C” (Combinations) or “P” (Permutations). Cell A2, put the number of items in the subset – in my case it’s 3. Cells A3 down, your list.  in my case (numbers from 15) My question is: ================ What changes do I need to make to this VBA code to get multiple combinations in just one go. Example: If I have C in A1, 3 in A2 and Numbers from 15 in the range A3:A7 and if I run the macro, it will give me all possible combinations of 3 in sheet2 If I have two conditions 1. If I have C in A1, 3 in A2 and Numbers from 15 in the range A3:A7 and if I run the macro, it will give me all possible combinations of 3 in sheet2 2. Lets say if I have C in B1, 3 in B2 and Numbers from 15 in the range B3:B7 and if I run the macro, it should give me all possible combinations of 3 in sheet2 in columns A and B == AND == Is it possible to put the output of the below given VBA code in ACCESS table in just one field instead of Sheet2 of the same worksheet? I have 21 names and I want to make a group of 7 people which totals up to 116280 (=COMBIN(21,7)). Instead of having 65536 names in column A of Sheet2 and 50744 names in column B of Sheet2, I want to put the entire 116280 names in an ACCESS Table in just one field.

The macro is written to expect all of the members of the population in a
single column, starting with the 3rd cell. What's the problem with copying the data from B3:B7 over to A8? As for sending the data to Access, AIR, you can do 2 imports from Excel to Access. (You may have to copy the 2nd column onto a 2nd worksheet.) It's possible to modify the macro to send the data to Access directly, but I can't see that it's worth my time to do it, particularly if this is a "onetime" need. Of course you are free to modify the macro as you wish. In fact, you could modify the code to run from Access, where the population members are in a table instead of on a worksheet, and the combinations are added to a new table. BTW, FWIW, it doesn't run "instantaneously" when the numbers of combinations or permutations is large <g.

Thank you for your reply.
I can copy the data from B3:B7 over to A8. I just asked that question out of curiousity. I can even export the data to ACCESS. I am not an expert in VBA, if you could please modify the code to either send the data to Access directly, OR if you could modify the code to run from Access that would be wonderful. Believe me its not a "onetime" job. I do all my work in ACCESS. Please modify the code and send it to me.

Sorry, but Access is not my "native tongue". It would take me several hours to
do this in Access. Perhaps you can find an Access or Excel consultant to do it for you. Chip Pearson does Excel projects; I don't know whether he does Access too, or what his rates are.

Hi Myrna, I Tried Running your Code for Combinations, But Kept Getting an Error on the Line : If Which = "C" Then AddCombination PopSize, SetSize <<< This Line <<< Else AddPermutation PopSize, SetSize End If vAllItems = 0 It Says "Expected Sub, Function or Property". I Tried to Dim it Along with Several Other Ideas, But to NO Avail. Would you be Able to have a Look at the Problem Please. Thanks in Advance. All the Best Paul
