A Second Infinite Skew Polyhedron

Here is the second polyhedron that Petrie presented to Coxeter in 1926. see - https://www.thingiverse.com/thing:2884052 - This polyhedron is composed of hexagons. The vertices of four hexagons meet at a point; the pattern is repeated in three dimensions to make a skew polyhedron. Like the previous polyhedron this pattern is a member of space group 229 with 4 hexagons as the repeating unit. However it is convenient to consider a unit cell containing eight hexagons arranged like a hollow trunca
