In geometry, the pentagonal antiprism is the third in an infinite set of antiprisms formed by an even-numbered sequence of triangle sides closed by two polygon caps. It consists of two pentagons joined to each other by a ring of 10 triangles for a total of 12 faces. Hence, it is a non-regular dodecahedron. (Wikipedia).

The Origins of Antisemitic Stereotypes | Unpacked
Antisemitism has always been around, but one thing’s for sure: Over the past few years, this centuries-old prejudice has taken on a more violent face in the U.S. This week, we’re unpacking some of the antisemitic ideas we see in America today and trying to identify the conspiracy theories

D. Davis - Periodic paths on the pentagon
Mathematicians have long understood periodic trajectories on the square billiard table. In the present work, we describe periodic trajectories on the regular pentagon – their geometry, symbolic dynamics, and group structure. Some of the periodic trajectories exhibit a surprising
