The 2-engine Cordership is a diagonal c/12 spaceship that was discovered by Aidan F. Pierce on December 31, 2017. It is the Cordership that uses the fewest number of switch engines known to be possible, as well as the smallest Cordership in terms of population.

Synthesis

Dave Greene found a 13-glider synthesis of the 2-engine Cordership on the day of its discovery, which AbhpzTa improved to 9 gliders.

Uses

David Bell built a 4-engine Cordership rake from two adjacent 2-engine Corderships on January 3rd, 2018.
