Wing: Difference between revisions
m for the record, I'm not completely sure that merging everything to one page was a better solution than (for example) keeping https://conwaylife.com/w/index.php?title=Nine&oldid=110867 separate. "No one seems to be arguing" is not identical to "everyone seems to agree". / This edit is formatting fixes. |
the name got changed back to prodigal; keeping both names and not replacing because this is the "nine" section |

- This article is about the evolutionary sequence. For the extensible c/4 diagonal spaceship, see Wing (spaceship).
- "Wing" can additionally refer to a group of switch engines which form half of a Cordership.

Wing is a common evolutionary sequence that stabilizes at generation 104 as a block and a glider. Its most common grandparent is traditionally referred to as block and glider, which is composed of two pre-blocks and has a lifespan of 106 generations. That pattern has a six-cell parent called nine, resembling an eater 1 with one tail cell missing.

Usage
Still life
Nine is a part of several still lifes, as shown in the table below.
Oscillator
A nine is hassled by two eater 1s in a period-4 oscillator, confused eaters.
Like other common evolutionary sequences, wings can be hassled, such as in the p25 wing and block hassler[note 1][note 2] and p128 wing shuttle.
Conduit
A number of conduits have been found to produce or accept a wing (abbreviated W) with reasonable clearance, such as PF35W and WFx46H. A WSW-3 conduit[note 3] can be made by eating the extra block using a block or eater 1.

Notes
- ↑ Catagolue: p25 wing and block hassler
- ↑ 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]
