Centinal

Centinal is a period-100 shuttle oscillator that was found by Bill Gosper no earlier than 1973 and no later than 1987, being the first oscillator of this period to be discovered. It combines the mechanisms of the period 46 and period 54 shuttles. It is able to reflect gliders by 90 degrees, a property that Gosper used to construct the p1100 MWSS gun.[1]

gollark: It seems vaguely unlikely to me.
gollark: What? I haven't heard of that.
gollark: So if it's before then and I don't lose a bunch of data it would obviously be possible to check such things.
gollark: I can check, I have a closed timelike curve connected to 2103.
gollark: The most interesting quantum thingy™ I'm aware of is Grover's algorithm, which seems to just magically be able to speed up some search-ish/brute-force things using magic.
