Tempest[1] is a period-4 oscillator that was found by Dean Hickerson in August, 1989 (4.0.3 in his oscillator stamp collection).[2]
It first appeared in an asymmetric soup submitted to Catagolue by Rob Liston on February 9, 2020.[3]
Commonness
- Main article: List of common oscillators
Information on this oscillator's commonness with respect to other naturally-occurring patterns is currently unknown.
Glider synthesis
A 19-glider synthesis was found by Jason Summers early on and is recorded in Mark Niemiec's database.[4] It has since been reduced to 12 gliders.[5]
