Retrieved on June 10, 2009. Stable converters have since been constructed that convert Herschels or gliders to switch engines and back. ![]() These 'swimmer tracks' were first constructed by David Bell in 2005. Like Herschels, switch engines can be supported by conduits made out of well-separated still lifes. 'Swimmer' tracks Main article: Switch engine channel ![]() Such spaceships can be constructed by combining as few as two switch engines. These spaceships move at c/12 diagonally and are thus the slowest known non- adjustable spaceships in Life. They are named "Cordership" in honor of Charles Corderman. It is also possible to create spaceships made of switch engines that interact to remove their combined exhaust. In addition to the puffers based on a single switch engine, puffers such as Noah's ark can be created by combining two switch engines. Switch engine-based puffers and combinations thereof, such as pony express and birthday puffer, are also the only infinite growth patterns observed to have emerged from asymmetric soups on Catagolue.īecause the switch engine lends itself so naturally to infinitely-growing patterns, it appears in many of the smallest known superlinear growth patterns, including the mosquitoes, catacryst, metacatacryst, Gotts dots, and 20-cell quadratic growth. These two puffers are the most natural infinite growth patterns in Conway's Game of Life, being by far the most common ones to occur from non-symmetric random starting patterns. There are two basic types of stabilized switch engine orbits, both of which were also found by Charles Corderman: the period-288 block-laying switch engine (the more common of the two), stabilizing in an orbit of six cycles (with additional glide symmetry) and period-384 glider-producing switch engine, stabilizing in an asymmetric orbit of eight cycles. The movement of a switch engine can be sustained in different types of patterns. If Corderman was examining polyominoes in order of size, then this smaller predecessor should have been found first in any case. It is the smallest known polyomino to do so.

There is, however, a unique nonomino switch engine predecessor whose 2-tick descendant matches that of a switch engine: However, record of the decomino switch engine predecessor seems to have been lost. Records indicate that he found the switch engine while investigating the decominoes (polyominoes having 10 cells). In 1971, Charles Corderman investigated the fate of all the small polyominoes exhaustively. If left unattended, the accumulating exhaust overtakes and destroys the engine after 24 cycles, but it can be stabilized to make c/12 diagonal puffers and spaceships. It produces a copy of itself after 48 generations, glide-reflected 4 cells northwest (starting in the form to the right), along with some active junk. #C ]Ī switch engine (or Corder engine ) is a methuselah that was found by Charles Corderman in 1971.
