Randomized trial classifies rank-2 hyperbolic root systems via integer pairs, indicating links to E8 symmetries.

To classify rank-2 hyperbolic root systems using integer pairs (a,b) under the condition ab ≥ 5.
Defined generalized Cartan matrix H(a,b) = [[2, -b], [-a, 2]];
Investigated non-symmetry conditions based on the values of a and b;
Examined the implications of the condition ab ≥ 5 on hyperbolic geometry.
Identified non-symmetric rank-2 hyperbolic root systems for pairs with a ≠ b;
Established that the integer condition ab ≥ 5 separates finite/affine from hyperbolic types;
Linked anisotropy in classification to phenomena akin to 60-fold symmetry breaking in hyperbolic lattices.
