The 7-in-a-row Cordership is a diagonal spaceship that was discovered by Dean Hickerson on July 23, 1998. It is one of the smallest known Corderships, and one of the Corderships with a known glider synthesis. It shares many properties with the 6-in-a-row Cordership.
Synthesis and destruction
A 48-glider synthesis for the 7-in-a-row Cordership has been known since June 2003, consisting of a 21-glider salvo meeting a 27-glider salvo. At that time a gun was constructed that fires 7-in-a-row Corderships; it is known as the V gun due to its shape.
This Cordership can also be eaten, as shown by the pattern below that was created on July 4, 2003, based on a glider-extraction 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.
