The 4-in-a-row Cordership is a c/12 diagonal spaceship that was discovered by wwei23 on September 9, 2020.[1] It is composed of four switch engines in a direct line. The interaction of the engines produces a period-doubling mechanism at the back of the spaceship, so that the period is 192 instead of the usual 96. This Cordership consists of two copies of a period-96 puffer seen in a custom apgsearch script that randomly arranged two switch engines and a block. The puffer itself creates an eater 1 and a block, but here they are arranged to remove their collective debris. Not surprisingly, this is how this spaceship was found.
Ian07 created a 14-glider synthesis of the new Cordership on the same day.[2] wwei23 constructed glider-to-4RC and 4RC-to-glider converters on September 17 and 18 respectively.[3][4]
