There have been a lot of new discoveries about superpermutations of late, but my absolute favourite is Andrei Teodorescu’s discovery of a length-5905 superpermutation on 7 symbols.
This is one shorter than the best that was previously known – and honestly one shorter than I would have guessed was possible.
