The American Institute of Mathematics, with the help of the Sage supercomputer at Washington University, has managed to complete, after 4 years of work, the mapping of the E8 to explain its symmetry. It is a 248-dimensional object belonging to a Lie group (the “E8” precisely) that can rotate around its own axis always appearing in the same way, as well as the dodecahedron (12 faces) and the icosahedron (20 faces) which also belong to the Lie group E8, the tetrahedron (4 faces), the cube (6 faces) and the octahedron (8 faces) belonging to the Lie groups E6 and E7, and finally, the sphere; the study can have important applications in the heterotic theory of 26-dimensional strings (reduced to 3 spatial and one temporal by rolling up 16 of them with a double use of E8 and then 6 in another way).
