Karel's p15 is a period-15 oscillator discovered by Karel Suhajda on December 11, 2002.[1] In this oscillator, a pentadecathlon hassles an unnamed active reaction. A pentadecathlon can support 2 Karel's p15s.
It provides accessible sparks that can be used to perturb reactions; the advantage of Karel's p15 over a pentadecathlon is that the pentadecathlon's long end reaches its maximum extent on two separate occasions, while Karel's p15 does only once, allowing its use as a T-nose. The p15 bouncer mechanism is an example. In the same month of its discovery, Mark Niemiec found an 18-glider synthesis of this oscillator.[2]
This oscillator first appeared semi-naturally in March 2015.[3]
A glider stream with period divisible by 5 but not 15 can be filtered with a Karel's p15 to triple the period.
