Talk:Trihedron

The redirection seems to need some clarification, since the page for hosohedron does not include the term trihedron or a definition of the term trihedron. There is some information on MathWorld about the notion of a trihedron, but it is minimal. I hope that someone who knows about trihedra will add a page for them, because I wanted to know more about their groups of symmetries, which apparently are called "trihedral groups".
