49P88 is an unnamed period-88 oscillator discovered by Paul Callahan on September 13, 1996. It consists of a pi-heptomino being hassled by six copies of eater 1. In terms of its 49 cells, it was the smallest known non-trivial period 88 oscillator until the discovery of figure eight on rattlesnake in 2016.
