Herschel parent is a parent of the Herschel and therefore is a methuselah that stabilizes after 129 generations. Compare with the similar (but much longer-lived) methuselah bunnies.

The right-hand domino can be removed without affecting evolution (producing a 6 cell parent), however the form shown is the parent produced by the B-heptomino.
