text: After the elimination of the icosahedral triangular faces, the remaining faces are the dodecahedral pentagonal faces and the triacontahedral faces which from octagonal become hexagonal, always non-regular but symmetric: the six sides of the hexagonal faces consist of four short sides and two long sides (ref: polyhedron i ).
