Caterer is a period-3 oscillator found by Dean Hickerson on August 4, 1989.[1] Its rotor is similar to that of jam. In terms of its minimum population of 12 this is the smallest period 3 oscillator, and tied with fox as the smallest wholly asymmetric oscillator.

More generally, any oscillator which serves up a bit in the same manner, such as T-nosed p4 and T-nosed p6, may be referred to as a caterer.


Caterer is about the forty-second most common naturally-occurring oscillator in Achim Flammenkamp's census, being about as frequent as beehive on griddle.[2] On Catagolue, it is the fourth most common period 3 oscillator, being less common than candlefrobra on trans-block but more common than candlefrobra on cis-block.[3]


An 11-glider synthesis of the caterer was discovered by Tim Coe;[4] Tanner Jacobi and Chris Cain later found a 7-glider synthesis.[5]
