Hi all. I prepared a small example database but it seems that I'm not allowed to post an attachment so I'll try and explain my dilemma by using one of the above tables.

This is a typical example of winning Lotto results over 7 draws of a 6-pick, 40-number lottery.
(The real database contains about 1500 draws).
I'm trying to find out if any of the 1500 results have ever been duplicated.
For example, rows 1,3 and 6 contain the same numbers.
But they're in different numerical order, as is almost certain to be the case in real life.
Could a formula recognize the duplicated 6 numbers even though their order is different?
 

Excel Facts

Format cells as date
Select range and press Ctrl+Shift+3 to format cells as date. (Shift 3 is the # sign which sort of looks like a small calendar).
You could use some worker columns.
The AGGREGATE puts the numbers in ascending sequence.
The concatenation gives a single cell to count (with "-" between so 3-34 isn't confused with 33-4).
The COUNTIF tells how many repeats there are.

Same idea, but with a UDF.

VBA:
Code:
Function ALSORT(r As Range) As String
With CreateObject("System.Collections.ArrayList")
    
    For Each c In r
        .Add c.Value
    Next c
    
    .Sort
    ALSORT = Join(.toarray, "-")
    
End With
End Function

Thanks guys. I just posted a longer reply but it seems to have disappeared, hence this post to see if it works...

Okay, I know what I did - clicked 'Reply to Thread' instead of 'Submit Reply'.

Toadstool: Ah, so it's necessary to put each row into numerical order before anything else? It occurred to me that one could then 'sort' column H into low-to-high which would sift the database into 1,x,x,x,x,x, 2,x,x,x,x,x etc groups from the top down. Though with a database of 1500 entries and 40 numbers I guess there'd be around 37 or so results (1500\40) in each group starting with 1, then 2 and so on. Your way's best! :rolleyes:

Irobbo341: Thanks for the alternative method. Would that work with a 1500 row database?
