C-heptomino

The C-heptomino is a methuselah (by shifting the top-left cell of the B-heptomino one cell right) that evolves in the same way as a B-heptomino after its second generation and thus evolves into three blocks, two gliders and a ship after 148 generations. It was named by John Conway. Despite this, it can't be used with the BFx59H due to reacting in its predecessor form shown in the p54 shuttle.
