P50 traffic jam is a period 50 oscillator discovered by Noam Elkies on October 16, 1994.[1] It works by hassling the 25-generation traffic jam reaction with two copies of fumarole and two copies of octagon 2. In terms of its 92 cells, it is the smallest known period 50 oscillator.[2] The version shown is the cis version, and by reflecting the right side it is possible to get a trans version with also 92 cells.
