Scot's p5 is a period5 oscillator that was found by Scot Ellison in June 2008. It has the seventh highest volatility of any known period5 oscillator, after the statorless p5, a fourfold variant of itself (that is the secondhighest), swine and three unnamed oscillators.
On September 28, 2023, KtT reduced the synthesis cost from 23 to 22 gliders,^{[1]}^{[2]} and then reduced the cost to 18 gliders on August 29, 2024.^{[3]}^{[4]}
