Code for the match - NOTE: duplicates will be double counted, but I did not
detect any duplicates in your sample so it should be OK as it is. If there
are more than 233 duplicate pairs in the any two row combination the
worksheet overflows! One way around this would be to put results into an
array and dedupe the list before writing back to the worksheet.

Sub Compare()
Dim r As Integer, rr As Integer, c As Integer, cc As Integer, opc As
Integer, opr As Long

opr = 1
For r = 1 To 16
For rr = r + 1 To 17
opc = 23
For c = 1 To 20
For cc = 1 To 20
If Cells(r, c) = Cells(rr, cc) Then
Cells(opr, opc) = Cells(r, c)
opc = opc + 1
End If
Next cc
Next c
opr = opr + 1
Next rr
Next r

End Sub

I want to compare the first set of 20 numbers (A1:T1) with the second
set (A2:T2) and check how many numbers match. ** If the matched numbers
are =10 ** then list them to the right of cell W1. In this example, 10
numbers matched are 4,9,10,21,35,47,64,72,74,75. List them in W1:AF1.

Now compare (A1:T1) with (A3:T3). In this example, 11 numbers matched
4,9,10,21,33,41,47,57,6,72,74 list them in W2:AG2.

Now compare (A1:T1) with (A4:T4). 10 numbers matched
3,4,10,11,21,32,33,35,60,69 list them in W3:AF3.

Compare (A1:T1) with (A5:T5). Here only 5 numbers matched 9,21,64,69,75
(Which is ** less than 10 ** - does not match the criteria) DO NOT LIST
this.

Compare (A1:T1) with (A6:T6). 11 numbers matched,
3,4,7,10,21,33,37,47,57,69,75 list them in cell W4:AG4.

Go on comparing (A1:T1) with all other sets of 20 numbers till
(A17:T17).

Once finished, start comparing (A2:T2) with (A3:T3), then (A2:T2) with
(A4:T4) ..... (A2:T2) with (A17:T17).

Once finished, start comparing (A3:T3) with (A4:T4), then (A3:T3) with
(A5:T5) ..... (A3:T3) with (A17:T17).

Go on doing this till (A16:T16) with (A17:T17).

Can anybody help?

Thanx
