Rich's p16 is a period 16 oscillator that was found by Rich Holmes on July 5, 2016 using Adam P. Goucher's apgsearch.[1] It consists of a bi-boat interacting with unnamed objects that then create two more boats, but flipped. It can slightly interact with a snake in a non-trivial way.[2] It can also act as a T-nose.

Tanner Jacobi and Michael Simkin used Rich's p16 on the day of its discovery to optimize various guns.[3][4]

Synthesis

Blinkerspawn found an 18-glider synthesis of Rich's p16 on the day of its discovery,[5] which Mark Niemiec noticed could be reduced to 17 gliders.[6] Martin Grant improved this synthesis to 16 gliders. Blinkerspawn subsequently found a 14-glider synthesis on June 27, 2017.[7]
