| The '''glider-producing switch engine''' (or '''glider-making switch engine''') is a [[puffer]] that was found by [[:Category:Patterns found by Charles Corderman|Charles Corderman]] in the early 1970's. It consists of a [[switch engine]] reacting with [[block]]s to produce various [[still life]]s and a [[glider]] every 384 [[generation]]s.
| |
| | |
| It is the second most common naturally-occurring pattern that exhibits [[infinite growth]], and is one of only two patterns that exhibits infinite growth that has been known to occur naturally (the other being the [[block-laying switch engine]]).
| |
| | |
| Because of its easy construction (see its predecessors below), it has appeared in some superlinear growth patterns including [[mosquito 3]].<ref>{{Cite web|url=http://www.argentum.freeserve.co.uk/lex_m.htm#mosquito3|title=Mosquito 3|author=Stephen Silver|publisher=The Life Lexicon|accessdate=June 1, 2009}}</ref>

| The '''time bomb''' (shown below) is a 17-[[cell]] [[pattern]] that was found by [[Doug Petrie]] that evolves into a glider-producing switch engine.<ref>{{Cite web|url=http://www.argentum.freeserve.co.uk/lex_t.htm#timebomb|title=Time bomb|author=Stephen Silver|publisher=The Life Lexicon|accessdate=May 16, 2009}}</ref>
