Wing (W in conduit names), also called block and glider, is a common evolutionary sequence that stabilizes at generation 104 as a block and a glider.
A WSW-3conduit can be made by eating the extra block using a block or eater 1.
The six-cell grandparent of the wing is technically a failed puffer, as it reappears 32 generations later shifted 3 cells right and 7 cells up only to be turned into a B-heptomino 3 generations later.
The term "block and glider" traditionally refers to the most common grandparent of the wing, which has six cells and a lifespan of 106 generations. That pattern has a six-cell parent called nine, although this name is rare. Confused eaters hassles this predecessor.
↑An alternative version of this oscillator is shown in jslife with a different method of stabilization.[1]Nicolay Beluchenko found the simpler stabilization with two fumaroles later on.[2] However, it is unknown when or by whom this reaction was found.[3]
