The 33.0 PG is cooked. That Rg8-g1-a1 cook works.
It doesn’t work with the 32.5 PG (with Ng2 —> e3) though, so it might be unique. Maybe.

Is there a name for this idea where the knight visits every knight square?
How about a simple one for a change? How fast can this position occur (with black to move since it's stalemate).

Here's my first try, 23.5 moves.
Now of course we have to do the reverse, to make it end in an even full number of moves!
short unique spg?
