Identify similar groups of numbers

I have sets of six numbers.

I have selected all possible groups of three from each set of six numbers.

I have to cross examine between sets in order to identify where there are similarities.

This means if I find a set of three numers (eg 15,60,75) in one set of six numbers (eg 15,20,50,60,65,75), I have to inspect all other sets of six numbers to try and find the same.

I have to do this for all possible sets of three numbers from all sets of six.

on the worksheet that I have attached, I have separated out the "sets of three" for visual purposes, as I also have to be able to look through this list like this.
I would like to colour the cells of similar "sets of three numbers" the same colour. But each set pair found after that would require a different colour to be applied.

Would it be possible (without altering the cells of the original sets of six) to go through all of these sets of three numbers and identify other identical sets ?

Looking at the data it seems that all sets of three have a duplicate since rows 3 and 4 are the same as 7 and 8. So if you run this code against that data all the sets of 3 will be highlighted, but maybe your real data is different.

Sub IdentifyDuplicates()

Dim lngLastRow As Long
Dim lngLastColumn As Long
Dim lngRow As Long
Dim lngCol As Long
Dim DupeSets() As Sets
Dim strSet As String
Dim lngFind As Long
Dim bFound As Boolean

ReDim DupeSets(0)
lngLastRow = Range("A65536").End(xlUp).Row
lngLastColumn = Cells.Find("*", SearchOrder:=xlByColumns, LookIn:=xlValues, SearchDirection:=xlPrevious).Column

For lngRow = 3 To lngLastRow
    If Cells(lngRow, 1) <> "" Then
        For lngCol = 9 To lngLastColumn Step 4
            strSet = Cells(lngRow, lngCol) & Cells(lngRow, lngCol + 1) & Cells(lngRow, lngCol + 2)
                    bFound = False

            For lngFind = 0 To UBound(DupeSets)
                If strSet = DupeSets(lngFind).strCells Then
                    bFound = True
                    Exit For
                End If
            If bFound Then
                Range(DupeSets(lngFind).strAddr).Interior.Color = vbYellow
                Range(DupeSets(lngFind).strAddr).Offset(0, 1).Interior.Color = vbYellow
                Range(DupeSets(lngFind).strAddr).Offset(0, 2).Interior.Color = vbYellow
                Range(Cells(lngRow, lngCol), Cells(lngRow, lngCol + 2)).Interior.Color = vbYellow
                DupeSets(UBound(DupeSets)).strCells = strSet
                DupeSets(UBound(DupeSets)).strAddr = Cells(lngRow, lngCol).Address
                ReDim Preserve DupeSets(UBound(DupeSets) + 1)
            End If

    End If
End Sub

Sorry, I left out some code when I posted.

I've attached a workbook that contains the code. Look in Module1. IdentifyDuplicates is a macro to which I have assigned ctrl+z, so if you enter ctrl+z from the sheet the macro will execute. You could also go into the code environment select the macro and press F5.
