I am having a trouble as follows:
say I have 1,2,3 3 numbers, I want to permutate them so it gives 11 12 13 21 22 23 31 32 33. But this List permutation only gives me 12 13 21 23 31 32 , with those self-repeating item group deleted.
Sorry to be stupid but really an’t figure it out. Thanks a lot for your kind help!
