I've seen this called a "Prism-expanded cuboctahedron," but i cant vouch for the accuracy of this as a description.

According to this ... http://books.google.com/books?id=rrI-AAAAYAAJ&pg=PA191&lpg=PA191&dq=pentacontahedron&source=bl&ots=UxSVaN3yJn&sig=PCdyzJPprOxTgyECE9IEUtrf7T8&hl=en&ei=3uxzTNutHYa-sAPe1dnICA&sa=X&oi=book_result&ct=result&resnum=4&ved=0CCMQ6AEwAw ... a pentacontahedron has 2 hexagonal faces :(

Ok... I give up ... for lack of a better name for the shape I will go with pentacontahedron ... which may also be a 13-zone zonohedron
Upon closer examination .. this solid is made up of Squares ... Rhombus ... and equilateral triangle shaped faces ... and I still do not know the proper name for this shape
Friz .. and others .. please be aware that since this solid is made up of squares and equilateral triangles ... this will not be a fair die as the square sides will have a higher probability of being rolled than the triangular sides will ... Can anyone show me the actual shape name of this shape? pentacontahedron does not seem to be a shape that I can find in any of my resources
