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]
