P72 quasishuttle is a period72 oscillator (a twin bees 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 18 generations the Bheptominoes are flipped into a centuries and a pair of blocks by unices, which then reacts with the blocks and figure eights to be flipped back into Bheptominoes in 61 generations, but with extra blocks. The extra blocks move the Bheptominoes forward without leaving extra centuries. Although this looks at first sight like a shuttle, it isn't really, because each side of the oscillator uses a different hassling reaction. Like a regular twin bees shuttle, it can reflect gliders.
