Burloaferimeter is a period-7 oscillator that was found by David Buckingham in 1972.[1] In terms of its 28 cells, it is tied with the three unnamed oscillators 28P7.1, 28P7.2, and 28P7.3 as the smallest known period 7 oscillator.[2] In terms of its 10×11 bounding box, it wins outright.
Etymology
According to Mark D. Niemiec[3], a loaf was called a Bread Loaf by his group, which then was abbreviated to Br'loaf, then became burloaf. "Burloaf" has a population of 7, which "measures" burloaferimeter's period.
Variant
 C4_4-symmetric quadruple burloaferimeter variant found by Apple Bottom on Catagolue on June 16 2017.[5] View animated image. RLE: here Catagolue: here |
A 28-glider synthesis for the variant on the left was discovered by Luka Okanishi shortly after,[6] and was improved to 24 gliders by Jeremy Tan on January 5, 2020.[7]
