P56 B-heptomino shuttle is a period 56 oscillator discovered in its original form (shown below) by David Buckingham sometime before May 1991,[1] being the first period 56 oscillator to be found. It consists of a B-heptomino being hassled by two blockers and two blocks. In terms of its 45 cells, it is the smallest known period 56 oscillator.[2]
