The great rhombicosidodecahedron is also known as the truncated icosidodecahedron (and, confusingly, several other names). Regardless of what it’s called, these pictures demonstrate that this Archimedean solid can be constructed using rhombic triacontahedra as building-blocks.
First, here’s one in the same color I used for the decagonal ring of rhombic triacontahedra in the last post:
The next one is identical, except I used “rainbow color mode” for it.
Also, just in case you’re curious, here’s the dual of this polyhedron-made-of-polyhedra — this time, colored by face-type.
These virtual models were all built using Stella 4d, software you may buy, or try for free, right here.
