Caterer on 44P7.2 is a period-21 oscillator composed of a caterer and the unnamed 44P7.2. In terms of its 56 cells, it is the smallest known non-trivial period 21 oscillator, although jam on 44P7.2 (pictured below) has a smaller bounding box.

Despite being composed of two oscillators of smaller periods (3 and 7 respectively), it is considered non-trivial because it has a single cell that is alive in generation 14 and is dead in its other 20 phases.
