This article is about the catalyst. For the spaceship, see Hivenudger.

Some reactions push a beehive one cell. The beehive push catalyst is a pseudo-still life that pushes the beehive back to its original location. It was originally discovered by Tanner Jacobi on December 20, 2020, using Bellman.

The following is an example of the beehive push catalyst in action. On the left, there is a single beehive, and it is pushed one cell forward. On the right, the catalyst pushes it back to its starting position.

Glider synthesis

A 126-glider synthesis for the beehive-push catalyst was found in August 2022,, and was then reduced to a 94-glider synthesis and a 87-glider synthesis the same day. Later, synthesis cost was reduced to 77 gliders, and then to 76 gliders.
