When a fan of a cult anime series wanted to watch its episodes in every possible order, they asked a question that had perplexed combinatorial mathematicians for years
Fascinating. But I wouldn’t count watching 1-2-3-1-2-1-3-2-1 as watching 1-2-3, 1-3-2, 2-3-1, 2-1-3, 3-1-2, 3-2-1. It might make sense for some applications, but for watching a series you’d really have to watch each permutation in full.

Why not? It’s the same thing, you just have to change your frame of reference as to which episode was ‘first’ for each permutation
