Snacker on 38P7.2 is a period 63 oscillator composed of a snacker and 38P7.2. Although it is composed of two oscillators of smaller periods (9 and 7 respectively), it is considered non-trivial because it has a single cell that is alive in generation 5 and dead in the other 62 phases of the oscillator. In terms of its 78 cells, it is the smallest known non-trivial period 63 oscillator.
