Hi,
I have the following VBA code from @Peter_SSs from another thread that generates unique combinations. However, the VBA omits combinations with repeated elements. For example, if I have elements A, B, and C then AA, BB, CC are omitted. I'm looking for some help modifying the VBA such that it retains the combinations with repeated elements. Thanks!

VBA Code:
Sub All2Combos()
  Dim a As Variant, b As Variant
  Dim i As Long, j As Long, x As Long, y As Long
 
  a = Range("A2", Range("A" & Rows.Count).End(xlUp)).Value
  ReDim b(1 To UBound(a))
  For i = 1 To UBound(a)
    If Len(a(i, 1)) > 0 Then
      x = x + 1: b(x) = a(i, 1)
    End If
  Next i
  ReDim a(1 To WorksheetFunction.Combin(x, 2), 1 To 1)
  For i = 1 To x - 1
    For j = i + 1 To x
      y = y + 1: a(y, 1) = b(i) & b(j)
    Next j
  Next i
  Range("C2").Resize(y).Value = a
End Sub
