The long bun is a somewhat common evolutionary sequence. While it had appeared in some tables of common sequences, it wasn't recognized as a distinct object until 2022.
Commonness
According to Simon Ekström's census of small evolving patterns[1], the long bun is the 12th most common qualifying sequence, appearing 48239 times on the list with a relative frequency of 0.078, similar to that of 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.[2] Predecessors typically converge in the generation that is generation 2 of the left object and generation 3 of the right object.

Use in oscillators
There are multiple oscillators that hassle the long bun. See Long bun hasslers for a complete list.
Miscellaneous
| When a long bun hits a block in a specific position, it forms a MWSS. However, this destroys the block (click above to open LifeViewer) |
| The object shown here that creates an anvil when it hits a boat-bit object (e.g. beacon, snake), by itself, becomes a long bun plus a loaf (click above to open LifeViewer) |
