- Not to be confused with Rob's p16.
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 due to its orthogonal thumb, although it is not counted among them.
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 on July 13.[7] BlinkerSpawn subsequently found a 14-glider synthesis on June 27, 2017,[8] and Alex Greason and Goldtiger997 together reduced the synthesis to 12 gliders on October 18, 2019.[9]
