By flops (or butterfly[1]) is a period-2 oscillator found by Robert Wainwright.[2]
This oscillator strongly resembles why not; indeed, it can be transformed into why not simply by placing an extra cell at one of the two Y-shaped appendages at a given side. Performing this on both sides gives why bother.
Commonness
- Main article: List of common oscillators
It first appeared naturally in Catagolue on May 21, 2015, in a soup submitted by Brett Berger,[3] after previously having been seen in Andrzej Okrasinski's census. Roughly 1 in 68.3 billion asymmetric soups contain this oscillator in their ash.
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.
