p3 bumper
p3 bumper is a variant of Tanner Jacobi's bumper found by Arie Paap in April 2018.[1][2] This bumper allowed Entity Valkyrie to make the new smallest p57 in October 2018. An alternate form of the period 3 oscillator catalyst (based on the caterer) is shown below. It uses a loaf, eater 1 and an edge-repair sparker.

For bounding box optimization purposes, it's also possible to replace the eater 1 with a 33P3.1, saving one row along the south edge at the cost of a higher population. This also works with a p6 bumper, p9 bumper, or p15 bumper.
