Metacatacryst is a 52-cell quadratic growth pattern found by Nick Gotts in December 2000. It is a modification of the catacryst (also found by Gotts) that contains six fewer cells but has a much larger bounding box. In terms of its 52 cells, it had been at one time the smallest known pattern that exhibits superlinear growth, but was superseded by 26-cell quadratic growth, which had been also found by Gotts.
Growth rate
Metacatacryst almost undoubtedly exhibits quadratic growth, but it is nowhere near as regular as other breeders. There is a form of expanding feedback loop, as switch engines deplete the gliders. An aperiodic sequence is generated by the resulting pattern of switch engines.
