A '''gunstar''' is any of a series of four-barreled glider [[gun]]s of period 144 + 72n (n ≥ 0) that were constructed by [[David Buckingham]] in [[:Category:Patterns found in 1990|1990]] based on his [[transparent block reaction]] and [[Robert Wainwright]]'s period 72 [[oscillator]] "[[47P72]]". Two copies of the oscillator together with a [[blocker]] and two [[eater 1]]s can duplicate a [[glider]]. One output glider emerges in the same direction as the original; the other is turned 90 degrees. By putting together 4 such reflectors, a 4-barrelled gun can be constructed.

A gunstar is any of a series of four-barreled glider guns of period 144 + 72n (n ≥ 0) that were constructed by David Buckingham in 1990 based on his transparent block reaction and Robert Wainwright's period 72 oscillator "47P72". Two copies of the oscillator together with a blocker and two eater 1s can duplicate a glider. One output glider emerges in the same direction as the original; the other is turned 90 degrees. By putting together 4 such reflectors, a 4-barrelled gun can be constructed.

The version to the right is the "first" such gun, with a period of 144. The next such gun, with a period of 216, is shown below.[1]
