The 7-in-a-row Cordership is a diagonal spaceship that was discovered by Dean Hickerson no later than 1998.[1] It is one of the smallest known Corderships, and is important because it is one of the Corderships with known glider synthesis.
[edit] Synthesis and destruction
The 48-glider synthesis for the 7-in-a-row Cordership is interesting because it consists of a 21-glider salvo meeting a 27-glider salvo (as opposed to gliders from various directions building the object step-by-step, as is usually the method of glider synthesis). Because it has a known glider synthesis, a gun has been 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. 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.
