Why not is a period-2 oscillator that was found by David Buckingham in July 1977[1] that is extremely similar to by flops; in fact, in one of its phases it differs by only one cell. It first appeared naturally on April 15, 2015, in a soup submitted to Catagolue by Brett Berger.[2]
Information on this oscillator's commonness with respect to other naturally-occurring patterns is currently unknown.
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.
