Is there a known record for the most possible stalemates in one in a legal position, for with and without promoted pieces? I did some constructing myself for a start.
For without promoted pieces, I found 105, counting different promotions as different moves.

For promoted pieces, I remembered a position from elsewhere on this site. I switched two pieces, made come counting deductions, and I arrived at a number of 205 moves for with promoted pieces.
