WebRecall that a lattice is a free abelian group equipped with a Z-valued non-degenerate symmetric bilinear form. The E 8 lattice is the unique positive de nite, even, unimodular lattice of rank 8. As the notation suggests, it is also the root lattice of the E 8 root system (which is the largest exceptional root system). The Weyl group of E 8 ...
