Mathematicians make even better never-repeating tile discovery

Mathematicians solved a decades-long thriller earlier this 12 months once they found a form that may cowl a floor utterly with out ever making a repeating sample. However the breakthrough had include a caveat – each the form and its mirror picture have been required. Now the identical group has found {that a} tweaked model of the unique form can full the duty in only one orientation.

Easy shapes equivalent to squares and equilateral triangles …
