Sombreros is a period-6 oscillator that was found by David Buckingham in December 1972.[1][2] Each half by itself is called a sombrero.
If the two sombreros are moved three spaces closer to one another then the oscillator's period drops to 4, and the result is just a less compact form of Achim's p4. Two sombreros moved one space closer and staggered by one space forms a period 5 oscillator called Siesta.
goldenratio found a 36-glider synthesis of a sombreros variant in October 2020.[3]
| If the sombreros are moved 3 cells closer together, a period 4 oscillator results (click above to open LifeViewer) |
