The **7-engine Cordership** is a c/12 diagonal spaceship that was discovered by Dean Hickerson on August 14, 1993. Until the discovery of the 6-engine Cordership almost five years later, it was the Cordership that used the fewest known possible switch engines. Corderships that use as few as 2 engines are now known.

This particular Cordership can be used to reflect gliders in a variety of ways. The image below shows two gliders that will be turned counterclockwise by 90 degrees (in red), a glider that will be reflected 180 degrees (in green), and a glider that will be turned into a southbound lightweight spaceship (in blue).^{[1]} For another method of performing a 180-degree glider reflection using the 7-engine Cordership, see glider loop.
