The long bun is a somewhat common evolutionary sequence. While it had appeared in some tables of common sequences, it wasn't recognized as its own distinct object until 2022.

Commonness

According to Simon Ekström's list of common evolutionary sequences, the long bun by itself is the 12th most common qualifying sequence, making its frequency similar to the I-heptomino, two-glider octomino, and procrastinator.

Predecessors and naming

The smallest predecessor of the long bun requires 7 cells; two examples are the infobox image and one of the two patterns below. The name "long bun" comes from David Raucci as the other predecessor below. Predecessors typically converge in the generation that is generation 2 of the left object and generation 3 of the right object.
