Pseudobarberpole on rattlesnake is a period 55 oscillator that is composed of a pseudobarberpole and rattlesnake. Although it is composed of two oscillators of smaller periods (5 and 11 respectively), it is considered nontrivial because it contains a single cell that is alive in generation 10 and dead in the other 54 phases of the oscillator. In terms of its 49 cells, it is the smallest known nontrivial period 55 oscillator.
