P50 traffic jam is a period 50 oscillator discovered by Noam Elkies on October 16, 1994. 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. 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.
