**The exceptional symmetry of E8**

Here's a little movie I made about the Lie group E 8 : Out of all the known Lie groups, E 8 stands out as the largest and most complex exceptional group. It has 248 generating elements, which by themselves have an astounding degree of symmetry. This symmetr...

Time for a pretty picture! It's the Weyl group of the finite Lie algebra

Although

*C4*.Although

*C4*is 'only' 36 dimensional, its Weyl group is a bit bigger and has 384 elements. The picture doesn't show the elements of the Weyl group though, but rather all possible connections between them. If you looks closely the black dots aren't dots -- they're points where are lots of lines meet.Add a comment...

An experiment in math publishing, using MathBox, explaining the often misunderstood subject of Complex Numbers.
