Beehive at beehive (or beehive tie beehive) is a 12-cell still life composed of two diagonally-touching beehives.
Glider synthesis
Beehive at beehive can be constructed with 4 gliders; several known syntheses can be found in Mark Niemiec's database.[1]

Commonness
- Main article: List of common still lifes
Beehive at beehive is the ninety-second most common still life in Achim Flammenkamp's census, being less common than ship on long boat.[2] In diagonal symmetries, including 8-fold symmetries, it is much more common, becoming the sixteenth through eighteenth (depending on the specific symmetry) most common still life.
It is the 89th most common still life on Adam P. Goucher's Catagolue, being less common than beehive on cap but more common than long boat tie ship. It is the 11th most common still life with 12 cells, being less common than beehive on table but more common than beehive with hooked tail.[3]
Beehive at beehive occurs in final patterns of 4 collisions from the octohash database[4] and 4 collisions from the octo3obj database.
