Honey farm is a common constellation of four beehives and is one of the familiar fours. It can be hassled in many ways.

In many cases, a block can eat a single beehive, but this is not the case for beehives from a honey farm. A fishhook can, though.

Predecessors

There are many predecessors to a honey farm[1], which can be hassled in different ways to give a large number of honey farm hasslers and honey farm shuttles.

A honey farm can be made from one beehive by placing a cell in the corner of it (making a bun, third one below), at the tip of it, or inside it (second one below). It also evolves from 7 cells placed in a row (first one below).

There are tens of six-cell patterns that form a honey farm, but none with five.

Below are four different ways a honey farm can form. Other than the line of seven, all are common. The predecessors converge in generations 2, 4, 5, and 6 from left to right; this predecessor is shown in red at the top. However, the generation prior to it, shown in red at the bottom, is different for all four of them.

Among the 2-glider collisions, three perpendicular and two head-on collisions form a honey farm.

Pulsar-forming reaction

As shown below, when two honey farms spaced at (9,0), (10,0), or (9,2) apart collide, they form two pulsars.

Useful glider-emitting reaction

When one particular generation of the honey farm sequence is sparked with a dot or domino spark in a specific location, or more commonly, is eaten by an eater 1, it releases a glider in addition to junk in the form of an interacting wing and lumps of muck. By itself, the reaction destroys the eater, but the junk can be manipulated to provide useful patterns, such as the Snark, 45-degree MWSS-to-G, and the smallest guns of periods 27, 37, 43, 48, 54, 55, 94, and 117.[note 1]

Notes

  1. There are some other honey-farm-based glider guns that are not the smallest of their respective period, such as p32 and p46.
