%N Table of Sprague-Grundy values for M X N Pop-It! hooks read by antidiagonals.
%C Pop-It! is played on an M X N lattice graph with a "pip" at each node. A move consists of popping any number of pips that are all collinear on the same horizontal or vertical line. A hook h(a,b) is defined as two lines of lengths a and b connected by a corner pip. The total number of pips of a hook h(a,b) is a+b+1.
%C This table seems to have similarities to A354586.
