Discovered by Noam Elkies
Year of discovery 1995

P156 Hans Leo hassler[note 1] is a period-156 traffic light hassler discovered by Noam Elkies on January 4, 1995.[1] It features two crowns turning a traffic light into a B-heptomino, and two eater 1s that then turn the B-heptomino back into a traffic light.

Elkies also found that the oscillator has several simple variants with an alternative phase of one of the crowns, leading to a period 144 version. It can even be made to be period 96 with figure eights, or period 132 with two copies of unix.

On November 10, 2019, Entity Valkyrie found a period 288 version of this oscillator.[2]
