Cha cha[1] is a period 2 muttering moat[2] oscillator, the long extension of clock.
Commonness
- Main article: List of common oscillators
This oscillator occurred in an asymmetric soup on Catagolue on July 17, 2022.[3][4]
In a somewhat unique case, on July 11, 2022 Charity Engine found a symmetric soup (in the symmetry C2_2) that produces this oscillator in an asymmetric manner, and the two halves of the soup do not interact throughout the evolution of the soup. As a result, by using the same seed for a C1 soup, an asymmetric soup producing cha cha can be made, making it ambiguous whether or not this oscillator qualified as "natural" at that time.[5]
Glider synthesis
All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
