p4 CP cenark

P4 CP cenark is a periodic colour-preserving glider reflector discovered by Tanner Jacobi in November 2017, with a minimum repeat time of 44 ticks.[1] A stable Snark reflector can be substituted for the p4 CP cenark. This slows down the output glider by three ticks, which can be useful for rephasing periodic glider streams. A p4 bumper can also be substituted to down the output glider by 8 ticks, but an equivalent adjustment can usually be made by moving a trombone slide one cell diagonally.
