Hey, I am trying to find the different combinations that can be formed by choosing 11 out of 22 objects ( i.e. C(22,11) ). I have posted below the code I tried using. the problem is that this code give me all possible combinations whereas I only need different ways in which 11 objects can be chosen out of 22.


VBA Code:
items(1) = "albert"
  items(2) = "pane"
  items(3) = "drey"
  items(4) = "max"
  items(5) = "pat"
  items(6) = "sam"
  items(7) = "shay"
  items(8) = "hem"
  items(9) = "asa"
  items(10) = "stone"
  items(11) = "sunderland"
  items(12) = "christian"
  items(13) = "hare"
  items(14) = "rob"
  items(15) = "sir"
  items(16) = "jamie"
  items(17) = "gray"
  items(18) = "khan"
  items(19) = "missy"
  items(20) = "seed"
  items(21) = "afb"
  items(22) = "cole"
  Set x = ThisWorkbook.Sheets.Add
  For a = True To False
    For b = True To False
      For c = True To False
        For d = True To False
          For e = True To False
            For f = True To False
              For g = True To False
                For h = True To False
                  For i = True To False
                    For j = True To False
                      For k = True To False
                        For l = True To False
                          For m = True To False
                            For n = True To False
                              For o = True To False
                                For p = True To False
                                  For q = True To False

                                            For v = True To False
                                              z = z + 1

Excel Facts

What do {} around a formula in the formula bar mean?
{Formula} means the formula was entered using Ctrl+Shift+Enter signifying an old-style array formula.
@natsu, are you aware that 11 of 22 different possibilities will yield 705432 different combinations?

= COMBIN(22,11)

@natsu, are you aware that 11 of 22 different possibilities will yield 705432 different combinations?
@johnnyL yes I am aware of that. When I ran the code above I got around 1 million combinations. So I wanted to change the code so that I get only 11 of 22 combinations which is 705432?

Pls check code below (after "Set x= ...."). Code is slow - generates about 60K string per minute without txt calculation
VBA Code:
For i01 = 11 To 22
  For i02 = 10 To i01 - 1
    For i03 = 9 To i02 - 1
      For i04 = 8 To i03 - 1
        For i05 = 7 To i04 - 1
          For i06 = 6 To i05 - 1
            For i07 = 5 To i06 - 1
              For i08 = 4 To i07 - 1
                For i09 = 3 To i08 - 1
                  For i10 = 2 To i09 - 1
                    For i11 = 1 To i10 - 1

  Z = Z + 1
  x.Cells(Z, 1).Value = Z
 
  ' txt = items(i01) & ", " & items(i02) & ", " & items(i03) & ", " & items(i04) & ", " _
         & items(i05) & ", " & items(i06) & ", " & items(i07) & ", " & items(i08) & ", " _
         & items(i09) & ", " & items(i10) & ", " & items(i11)
  ' x.Cells(Z, 2).Value = txt
 
                    Next
                  Next
                Next
              Next
            Next
          Next
        Next

Hey Gior. Thanks for your response I did get 705432 outcomes but none of them had the names listed on them. Only the numbers were listed from 1 to 705432. Can you help me with this?

Hi,​
is this a question to just know the number of combinations (instant result) or to generate / list all those combinations the quickest way possible ?​
