In followup to John Baez’ G+<\/a> thread on Hyperbolic Dynkin diagrams<\/a>, specifically on the only rank 4 compact symmetrizable diagram 136, I used my “VisibLie” notebook<\/a> (which includes the “SuperLie” package<\/a> for analyzing Lie Algebras) to get the following information:\ufeff<\/p>\n

\"H136_detail3\"<\/a><\/p>\n

Using the “SimpLie” Google Code OpenSource software<\/a>, we get Hasse diagram of:
\n\"Projection<\/a>
\nSymmetrized Cartan matrix:
\n 1 -1 0 -1\/2
\n-1 2 -1 0
\n 0 -1 2 -1
\n-1\/2 0 -1 1<\/p>\n

One possible set of basis vectors for this is:
\nsrH136={{0,2,0,0},{0,-1,1,0},{0,0,-1,1},{Sqrt[-7],-1,-1,-3}};<\/p>\n

with 4D angles between each node of:
\n{{1->2,135.},{2->3,120.},{3->4,135.},{4->1,120.},{1->3,90.},{2->4,90.}}<\/p>\n

Norm’d Length between nodes is:
\n{2, Sqrt[2], Sqrt[2], 2}<\/p>\n

as visualized in 2D and 3D, with 42 vertices and 26 edges of Norm’d 4D length of 2 and 94 at Sqrt[2]:
