For polyedron I thought I could find something in RhinoPolyhedra

http://www.food4rhino.com/app/rhinopolyhedra

but no luck, it is not a classical polygon. 

But the geometry of this tessalation is quite simple, there are many symetries in 3 main planes. So I used arcs rotated 45° from the main planes and I generate a pentagon which was mirrored and rotated many times.

At the end there are 24 pentagons and 8 hexagons so 32 faces, 54 points/vertex and 84 edges. 

It could generate some others tessalation styles
