text: Successively the hexagonal faces deform again, lengthening progressively along a direction orthogonal to the direction along which they were stretched previously (ref: polyhedron k , in which the hexagonal faces consist of four short sides and two long sides), until the truncation eliminates also the pentagonal faces: at this point the resulting polyhedron includes only the rhomb-triacontahedral faces (ref: polyhedron l ).
