Key Points

This research explores how theta functions of the E8 lattice serve as modular forms, linking various mathematical theories.
Analyzed theta function B8E8(\tau) for E8 lattice using modular forms of weight 4 for SL2(Z).
Utilized the Selberg trace formula for SL2(R) to connect spectral data to lattice enumeration.
Investigated the properties of the E8 lattice and its relationship with automorphic forms.
The E8 lattice possesses 240 shortest vectors with norm 2; its theta function expansion starts with 1 + 240q^2 + 2160q^4.
Theta functions demonstrate modularity, reflecting self-duality and evenness characteristics of the lattice.
The symmetry group related to the E8 lattice is the Weyl group with an order of 696729600.
