This is a commonly-used trick to reduce the period of many oscillators with signals traveling in a loop. See for example many of the guns in the glider guns thread .

I've moved this series of posts to the "unsure discoveries" thread, since it doesn't seem to need its own thread.


Okay sure that ...

It is possible to make, using any variations of the Snark , to create an oscillator of period-232, -116, another -232, and -58 oscillator by putting 1, 2, 3 or 4 gliders respectively in this loop:

# shown for 2 gliders (Period-116):
# using 4 variants of the Snark;
x = 51, y = 52, rule = B3/S23
#C ...
