The B-heptomino is a very common methuselah that evolves into three blocks, two gliders and a ship after 148 generations. Compare with herschel, which appears at generation 20 of B-heptomino's evolution. It often arises with the cell at top left shifted one space to the left, which does not affect the subsequent evolution. B-heptominoes acquired particular importance in 1996 due to David Buckingham's work on B tracks.
