Beehive with nine is a 12-cell still life.
This still life is comprised of the normally stable beehive with a normally unstable nine attached.
It can be substitutively referred to as the integral with beehive, with one pre-block of the integral sign replaced with a beehive, however "beehive with nine" is usually preferred for this object.

Commonness
- Main article: List of common still lifes
Beehive with nine is the eighty-ninth most common still life in Achim Flammenkamp's census, being less common than beehive with hooked tail but more common than ship on long boat.[3]
It is the 95th most common still life on Adam P. Goucher's Catagolue, being less common than 15-bent-paperclip but more common than very long barge. It is the 13th most common still life with 12 cells, being less common than beehive with hooked tail but more common than boat tie long boat.[4]
There are two collisions in the octo3obj database where beehive with nine occurs in the ash.[5]
