%N Number of still-lifes synthesizable from n gliders in Conway's game of Life.
%C No stable form can be produced by a single glider (on an infinite or toroidal board), thus a(1) = 0.
%C Block, boat, beehive, loaf, eater, and pond are the six still-life forms that can be made from 2 gliders.
%C Tub, Ship, Barge, Long boat, Mango, Long barge, Very long boat, Hat, Half bakery, Paperclip, and Bi-pond can be made from 3 gliders.
%C Most of the terms in this sequence are conjectural and will likely increase over time. - _Nathaniel Johnston_, Dec 03 2019
