Switch engine ping-pong is a quadratic growth pattern that was found by Michael Simkin on October 29, 2014. In terms of its 23 cells it is the smallest currently known quadratic growth pattern, superseding the previous record holder, 24-cell quadratic growth, also found by Simkin a week earlier.
It is the first such pattern found that uses only 2 switch engines.
