Fumarole on Achim's p11

Fumarole on Achim's p11 is a period-55 oscillator composed of a fumarole and Achim's p11. Although it consists of two oscillators of smaller periods (5 and 11 respectively), it is considered non-trivial because it contains a single cell that is alive in generation 31 and dead in the other 54 phases of the oscillator. In terms of its 90 cells, it was the smallest known non-trivial period 55 oscillator until the discovery of pseudo-barberpole on rattlesnake in 2016.
