Fumarole on Beluchenko's p13 is a period-65 oscillator discovered by Nicolay Beluchenko in January 2009[1] that is composed of a fumarole and Beluchenko's p13. Although it is composed of two oscillators of smaller periods (5 and 13 respectively), it is considered non-trivial because it contains a single cell that is alive in generation 51 and dead in the other 64 phases of the oscillator. In terms of its 52 cells, it is the smallest known non-trivial period 65 oscillator.
