Silver's p5 is a period-5 oscillator that was found by Stephen Silver on February 17, 2000 .[1] 17 cells pseudo-barberpole and octagon 2 . As it has no spark , it appears upon first glance to be useless. Nonetheless, in March 2000, David Eppstein found a way to use it to reduce the size of Noam Elkies ' period 5 reflector .
The version in the infobox shows a snake being used in the oscillator; the snake can be replaced with other still lifes such as an aircraft carrier or an eater 1 , or a beacon supporting (and being rephased by) four copies of it.

Commonness See also: List of common oscillators A version of this oscillator with an eater 1 first occurred naturally on January 5, 2016 , in a soup submitted to Catagolue by Adam P. Goucher .[5] stator variants have since occurred naturally.[6]
Glider synthesis In May 2007 Mark Niemiec found a 14-glider synthesis of a variation of this oscillator that uses an aircraft carrier rather than a snake for stabilization. On September 3, 2020 , goldenratio and Tanner Jacobi found an 8-glider component that adds a Silver's p5 rotor to a given still life,[7] Martin Grant later the same day.[8] cheapest known variant , using an eater 1 , therefore costs 8 gliders
