P4 bumper is a periodic colour-preserving glider reflector with a minimum repeat time of 36. A stable Snark reflector or p4 CP cenark can be substituted for the p4 bumper. This changes the timing of the output glider, which can be useful for rephasing periodic glider streams. For colour-changing period-4 reflectors, see p4 CC cenark and p4 bouncer.
