AB: Is this one C+? If so, it is impressive for its time. (2001-10-17)
GW: The game is not unique (for example moves 14 and 15 may be exchanged). I am also quite sure that there are different ways to reach the position, but nevertheless the problem is very impressive. (2001-10-17)
Francois Labelle: My computer says there are 272810 solutions (292397 solutions without Article 1.3 of the Laws). The minimum is 4 solutions for a (1+1) SPG in 17.0 moves. (2004-02-03)
