Hi,
I need to list all possible combinations of an array:
A1 B1 C1 D1 E1
A2 B2 C2 D2 E2
A3 B3 C3 D3 E3
The problem is, I need to list all the combinations of 1 to 5 values i. e. from A1 > through > B2 C3 E2 > till > A3 B3 C3 D3 E3,
without repetition of a column in a single result.
I mean I need to exclude results which contain the same letter twice - like A1 A2 or B2 B3 D3 or C1 C2 C3 etc.
Does anyone have an idea?
Many thanks!
