Mathematicians have discovered a close relative of "the hat," an aperiodic tile that does not repeat itself when tiled, that is a true chiral aperiodic monotile. The new shape, called a Spectre, is strictly chiral and admits only non-periodic tilings even when reflections are permitted. The team found that modifying the edges of the newly discovered polygon in certain ways creates a whole family of shapes, all strictly chiral aperiodic monotiles.

Researchers have discovered a new-and-improved "einstein" - a single shape that tiles a plane, or an infinite two-dimensional flat surface, but only in a nonrepeating pattern. The new monotile discovery does not use reflections and is a close relative of the original "hat" einstein. The team produced a family of strong or "strictly chiral aperiodic monotiles" through a simple modification of the T(1,1) tile, named "Spectres," which only allow nonperiodic tilings, and without reflections.
