Thanks to everyone who took part. I received 21 answers, 19 of which were correct. I know from correspondence that I stumped a number of good solvers, as well. It was admittedly a tough meta. Anyway, the randomly-selected prize winner is Dominick Talvacchio, who chose as his prize a 2015 subscription to MGWCC. An explanation of the meta can be found at
