Above, it would be good to make it obvious that all the elements have the same shape, namely 23: each one comprises a 2-cycle and a 3-cycle. But this is not obvious, because the order given by nicify_cyclist() tries to put the 1 first. It might be possible to force the print method to put the cycles in increasing (or decreasing) order of size.
