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 containing four gliders, with a total signal path length of 216+8N and therefore adjustable to any period of the form 54+2n. However, this is the smallest loop that can contain eight gliders, which is a requirement for universal adjustability.
