It works by bouncing a glider back and forth between the 13-engine Cordership and a fixed reflector; the round trip time doubles with each trip. Whenever the glider hits the fixed reflector, an extra glider is created; these gliders eventually dominate the population. The form shown to the right is a smaller version that uses a 7-engine Cordership and was found on September 2, 1994.

Its population in generation t is asymptotic to 5log(t)/log(2). More specifically, for n ≥ 0, the population in generation 960(2n) is 5n + 376.
