Burloaferimeter is a period 7 oscillator that was found by David Buckingham in 1972. 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.[1] In terms of its 10×11 bounding box, it wins outright.


According to Mark D. Niemiec[2], 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.
