The 3-engine Cordership is a c/12 diagonal spaceship that was discovered by Paul Tooke on January 12, 2004. Until the 2-engine Cordership was found, it was the Cordership that used the fewest number of known possible switch engines. Despite this, the 4-engine Cordership is smaller in terms of minimum population (the 2-engine Cordership beating both).
David Bell discovered in 2005 that the 3-engine Cordership can be used to turn a lightweight spaceship 90 degrees as shown below.[1] It could be constructed with 15 gliders, and Tooke created a gun for this spaceship only a week after its original construction (see 3-engine Cordership gun). In March 2017 Luka Okanishi discovered a three-glider synthesis for a switch engine, which reduced the recipe to only 11 gliders.[2]
The 3-engine Cordership can easily be destroyed by three eater 1s and four blocks, as shown below. This cleanup reaction was found by Jason Summers.
Incremental construction
Dave Greene discovered a glider synthesis for upgrading a switch engine to a wing, which can be repeated to form the complete Cordership. Adam P. Goucher then built a Herschel conduit to convert a glider into a 3-engine Cordership.[3]
