P7 bumper is a periodic colour-preserving glider reflector with a minimum repeat time of 35 ticks. For an equivalent colour-changing periodic glider reflector see p7 bouncer. A stable Snark reflector can be substituted for any bumper. This changes the timing of the output glider, which can be useful for rephasing periodic glider streams.
The 38P7.2 can be replaced with the 37P7.1, allowing a lower population but larger bounding box. This variant is used in the p49 bumper loop, the smallest known period 49 oscillator with only 206 cells.
