VBA Code:

On Error GoTo errHandler

Dim rRng As Range, p As Integer, lRow As Long
Dim vElements, vresult As Variant
lastRow = Cells(Rows.Count, "A").End(xlUp).Row
lRow = 0
Set rRng = Range("A1:A" & lastRow)
rRng.Select

If CInt(Range("C19")) = 0 Then
MsgBox "Enter amount of numbers to be in combinations"
Exit Sub
End If

 Dim q As Integer
          Dim b As Double
          b = 1
          For q = 0 To p - 1
                    b = b * (lastRow - q) / (p - q)
          Next q
MsgBox "No of Non repeating combinations is -> " & b, vbInformation
vElements = Application.Index(Application.Transpose(rRng), 1, 0)
ReDim vresult(1 To p)
Columns("D").Resize(, p + 15).Clear
Call CombinationsNP(vElements, p, vresult, lRow, 1, 1)
Exit Sub
errHandler:
MsgBox "Error has occured - error no " & Err.Number & " - " & Err.Description
End Sub


Sub CombinationsNP(vElements As Variant, p As Integer, vresult As Variant, lRow As Long, iElement As Integer, iIndex As Integer)
Dim i As Integer, k As Integer
On Error GoTo errHandler
For i = iElement To UBound(vElements)
    vresult(iIndex) = vElements(i)
    If iIndex = p Then
        For k = LBound(vresult) To UBound(vresult)
               Next
        lRow = lRow + 1
        Range("D" & lRow).Resize(, p) = vresult
       End If
       testRow = testRow + 1
       If iIndex <> p Then
        Call CombinationsNP(vElements, p, vresult, lRow, i + 1, iIndex + 1)
        End If
Next i

Exit Sub
errHandler:
MsgBox "Error has occured - error no " & Err.Number & " - " & Err.Description
End Sub

Lock one reference in a formula
Need 1 part of a formula to always point to the same range? use $ signs: $V$2:$Z$99 will always point to V2:Z99, even after copying
