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 is important because it is one of the Corderships with known glider synthesis.
Synthesis and destruction
The 48glider synthesis for the 7inarow Cordership is interesting because it consists of a 21glider salvo meeting a 27glider salvo (as opposed to gliders from various directions building the object stepbystep, as is usually the method of glider synthesis). Because it has a known glider synthesis, a gun has been constructed that fires 7inarow 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 gliderextraction reaction found by Karel Suhajda. It 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.
