The p43 snark loop is a period-43 oscillator made from Snark reflectors. It is the smallest of an infinite family of Snark-based adjustable glider loops that can have any period from 43 up. (There are much smaller glider loops made from four Snarks, but this is the smallest loop that can contain eight gliders, which is a requirement for universal adjustability.)
