Figure eight on centinal is a period-200 oscillator that is composed of a figure eight and centinal. Although it is composed of two oscillators of smaller periods (p8 and p100 respectively), it is considered non-trivial because it contains a single cell that is alive in generation 135 and dead in the other 199 phases of the oscillator. In terms of its 82 cells, it was the smallest known non-trivial period 200 oscillator, before discovery of figure eight on 30P25.
