Beehive at loaf is a 13-cell still life composed of a diagonally-touching beehive and loaf.
Construction
Beehive at loaf is known to be constructible with 4 gliders.[1] A 4-glider synthesis was found in August 2017.[2] Several known syntheses can be found in Mark Niemiec's database.[3]

Occurrence
- See also: List of common still lifes
Beehive at loaf is the sixty-sixth most common still life in Achim Flammenkamp's census, being less common than cis-bookend and bun but more common than tub with long tail.[4]
It is the 64th most common still life on Adam P. Goucher's Catagolue, being less common than long shillelagh but more common than trans-bun and wing. It is the most common still life with 13 cells, being more common than cis-loaf on table.[5]
They sometimes appear when a bakery is suppressed by a three-cell leading edge of an object, but this is not the only way they form.

There is a three-glider collision with beehive at loaf in the final pattern.[6] There is an occurrence of this still life in the ash of a collision between a glider and the B-heptomino sequence,[7] accounting for three other 3G collisions. Beehive at loaf occurs in final patterns of one collision between a glider and a stationary constellation catalogued in the octohash database[8] and 12 collisions catalogued in the octo3obj database.
