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.[1]

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,[2], and was then reduced to a 94-glider synthesis[3] and a 87-glider synthesis[4] the same day. Later, synthesis cost was reduced to 77 gliders, and then to 76 gliders.[5]
