Definitions

A particular symmetric seven-cell methuselah in Conway's Game of Life.

Examples

“A growing spaceship which uses the pi-heptomino.”

“It does include a pseudo-spaceship based on the Pi-heptomino (pseudo because it needs some classic spaceships in front, and so the middle gets longer and longer.”

“1) gliders on paths *adjacent* to the six annihilating paths produce a pi-heptomino and consequent large explosion -- and there's no way to place blocks on nearby lanes to catch those gliders, because they'd interact messily with gliders on some of the original six glider paths;”
