Why not is a period-2 oscillator found by David Buckingham in July 1977.[1]

This oscillator resembles by flops very strongly; indeed, by flops 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

It first appeared naturally on April 15, 2015, in a soup submitted to Catagolue by Brett Berger.[2] Roughly 1 in 146 billion soups contain this oscillator in their ash.

Glider synthesis

Goldtiger997 found an 8-glider synthesis for the oscillator on August 23, 2016,[3] and reduced the cost to 7 gliders on January 21, 2019 with a new script for 3-glider collisions.[4]
