P56 Bheptomino 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 Bheptomino being hassled by two blockers and two blocks. In terms of its 45 cells, it is the smallest known period 56 oscillator.^{[2]} The blockers interact with the B twice, once to supress the block, and another time to prevent the formation of a Herschel.
