258P3 on Achim's p11
258P3 on Achim's p11 is a period-33 oscillator composed of 258P3 and Achim's p11. Although it is composed of two oscillators of smaller periods (3 and 11 respectively), it is considered non-trivial because it contains a single cell that is alive in generation 21 and dead in the other 32 phases of the oscillator. It was discovered by Noam Elkies on June 25, 1997 and was the first period 33 oscillator to be found.[1]
