Finding links the E8 lattice's golden ratio to icosahedral quasicrystals, suggesting deep geometric connections.

This research aims to demonstrate the relationship between the E8 lattice and icosahedral quasicrystals through the golden ratio.
Analyzed the E8 root system and its H4 subgroup for structural constants.
Investigated the geometric properties and projections of E8 to H4 and their correlation with quasicrystal symmetry.
Calculated the symmetry group orders and identified ratios involving the golden ratio in various dimensional projections.
E8 lattice contains the golden ratio (φ) as an eigenvalue in the Cartan matrix, linking it to the H4 subgroup.
Icosahedral quasicrystal symmetry reflects the properties of the E8 lattice through geometric projections.
The analysis reveals intrinsic structural relationships where φ appears in the coordinates of the H4 root system.

Andrew Stewart Caldin (2026) studied this question.
