comment Showing two matrices are similar
@Henning Sorry. I am following a physics book and these matrices are actually representations. Two representations were defined to be equivalent if their matrices are related by a similarity transformation. This was what I had in my mind.

comment Showing two matrices are similar
Yes, I am sure. The first three matrices are what physicists call spin 1 representation. The final three matrices are the adjoint representation of SU(2) (excluding a phase factor of -i). The question is to show that the two representations are equivalent (a result which is used later to construct roots). I phrased only the computational part in my question.

@J.M. But we're talking about polygons not polyhedrons.

comment Is there a binary spigot algorithm for log(23) or log(89)?
I'm wondering why I got notified without @. Anyhow, regarding the above comment, what has your reputation got to do with it?

comment Calculating the matrix
hmm... going over wikipeidia, there's another method.. to use $ e^{A}Be^{-A}=B+[A,B]+\frac{1}{2!}[A,[A,B]]+\frac{1}{3!}[A,[A,[A,B]]]+\cdots $
