Mathematics

Regular 56-gon, associated by the Pythagoreans with Typhon

56 is:

Plutarch[7] states that the Pythagoreans associated a polygon of 56 sides with Typhon and that they associated certain polygons of smaller numbers of sides with other figures in Greek mythology. While it is impossible to construct a perfect regular 56-sided polygon using a compass and straightedge, a close approximation has recently been discovered which it is claimed[8] might have been used at Stonehenge, and it is constructible if the use of an angle trisector is allowed since 56 = 23 × 7.[9]
