Problems: record for most mates-in-2 Does anyone know what the record for most mates-in-2 is for a composed problem?

Example: this one has 58 different moves that mate in 2.

[FEN "6R1/8/8/8/3Q3B/5K2/7k/1R6 w - - 0 1"]
Sir Jeremy Morse, in Chess Problems: Tasks and Records, Introduction, cites this construction by E. Luukonen:

[Title "E. Luukonen, Uusi Suomi, 1936"]
[fen "kr6/pnPPPPPPPP/P2N4/R7/3BBN2/1Q6/3K3P/6R1 w - - 0 1"]

All of White's 117 moves lead to mate in 2. White has no mate in 1, but if Black's rook were to move, or if (after White captures that rook) Black's king were to recapture, White then has a mate. Thus a waiting-move is enough.
