Beehive is a 6-cell still life. It can be seen as a weld of two tubs. It was found by the JHC group in 1970.[1]
Commonness
The beehive is the second most common still life in Achim Flammenkamp's census, being less common than block but over three times as common as loaf.[2] The beehive is also the third most common object on Adam P. Goucher's Catagolue. It is the most common 6-bit still life, being more common than the ship.[3]
Behaviour
Beehives are frequently born in a set of four called honey farm.
It is possible to turn a single beehive into one by adding a corner (turning it into a bun), adding a cell to the "tip" of it (the bit with one cell, adding it to the longer end will result in a R-pentomino grandson) or by adding one cell inside it. There are also formations of two beehives that also occur fairly commonly, evolving from seeds known as butterfly and teardrop.
A beehive can be eaten with a block, a reaction that allows the construction of the queen bee shuttle and further patterns based on it.
