EXTRACTED METHOD: e8_root_to_600cell_mapping — E8 Intelligence Research
rule: Map each of the 240 E8 roots to the 120 vertices of the 600-cell (each vertex corresponds to a pair of opposite roots). Compute edge-length ratios between adjacent vertices; classify ratios into families (phi, sqrt(2), etc.). source: rlab #269 Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the...
