Hello Ben and Herve, I'm not sure if you already know but there's a previous
submission for combinations and permutations (mine) in the sequence_algo
folder of the sandbox. In fact, Herve helped out! :-) I've been away from it
for five years. Check out the discussion thread in the
archives. Nevertheless, I like your implementation. It's interesting that
you chose a sorting method similar to mine, instead of using a parallel
index array.
