The 7inarow Cordership is a diagonal spaceship that was discovered by Dean Hickerson on July 23, 1998.^{[1]} It is one of the smallest known Corderships, and one of the Corderships with a known glider synthesis. It shares many properties with the 6inarow Cordership.
Synthesis and destruction
A 48glider synthesis for the 7inarow Cordership has been known since June 2003, consisting of a 21glider salvo meeting a 27glider salvo. At that time a gun was constructed that fires 7inarow Corderships; it is known as the V gun due to its shape.
Due to Luka Okanishi's discovery of a threeglider switch engine synthesis in 2017, the 7inarow Cordership can now be constructed with only 25 gliders.
This Cordership can also be eaten, as shown by the pattern below that was created on July 4, 2003, based on a gliderextraction reaction found by Karel Suhajda which might be considered a Cordership Heisenburp, since the Cordership passes by the tub catalyst without being permanently affected. The Cordership eater consists of seven eater 2s and two tubs to do the majority of the eating, along with some Herschel tracks that produce gliders to clean up some blocks that are left behind.
A much more compact eater, or an equally compact Cordershiptoglider converter, can now be constructed thanks to the subsequent discovery of the Snark reflector and the syringe.
