P72 quasishuttle is a period 72 oscillator (a twin bee shuttle variant) with found by Jason Summers in August 2005. It consists of two Bheptominoes being hassled by two figure eights and two unices. In about 20 generations the Bheptomino is flipped into a century, which is then flipped back into a Bheptomino. Although this looks at first sight like a shuttle, it isn't really, because each side of the oscillator uses a different hassling reaction.
