Wing, or R-loaf, is a common induction coil which can be analysed as a loaf with an extra cell added as to make it asymmetric.

Wing-wing still lifes

As mentioned previously, it can act as an induction coil. Two wings suffice to make a still life, with five possible isomers:

Cis-mirrored wing
Trans-mirrored wing
Shift-mirrored wing
Cis-rotated wing
Trans-rotated wing

A sixth still life exists in which physical connection between both wings exists:

Wing bridge wing

As an evolutionary sequence

The wing is also a very common evolutionary sequence. In the form shown in the infobox to the right, it stabilizes at generation 104 as a block and a glider. A WSW-3 conduit can be made by eating the extra block using another block or eater 1.

One of its predecessors, the block and glider, is technically a failed puffer, as it reappears thirty-two generations later having been shifted 3 cells right and 7 cells up, but is turned into a B-heptomino another three generations later.

Like other common evolutionary sequences, the wing can be hassled, such as in the p25 wing and block hassler[note 1] and p128 wing shuttle;[4].

As a still life component

One of its predecessors, the nine, is a common still life component that is normally unstable. It can be attached to many still lifes or unstable components.

A green background indicates that the object the nine is added to is stable without it; a red background indicates this is not the case.

Notes

  1. ↑ 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]
