Dodecahedral cupola

In 4-dimensional geometry, the dodecagonal cupola is a polychoron bounded by a rhombicosidodecahedron, a parallel dodecahedron, connected by 30 triangular prisms, 12 pentagonal prisms, and 20 tetrahedra.[1]

The dodecahedral cupola can be sliced off from a runcinated 120-cell, on a hyperplane parallel to a dodecahedral cell. The cupola can be seen in a pentagonal centered orthogonal projection of the runcinated 120-cell:

gollark: > do people have these problems in other countries?In the UK, we have *different* problems.
gollark: Meh, I turn that off anyway because it seems to be more "Microsoft-approved boot" than *secure* boot. Unless you bother to set your own keys, I guess.
gollark: No, I did, several times.> The data/body can be large, contain arbitrary bytes, and is actually meant to store large amounts of data.> - servers may allocate limited-sized buffers for incoming request headers so you can't put too much in them (this is somewhat problematic for cookies)> request bodies can probably be handled more performantly because of stuff like the length field on them> - request bodies are generated by forms and all sane clients so stuff is mostly designed to deal with those
gollark: I did say multiple times why that's not really a good idea.
