The two data files relating to Humbert intersections are: humbert-intersections-ros.txt (3.68MB) Rosenhain Humbert intersections - HIros[i][j] gives the list of resultant factors found where we fix component of H_i and intersect with components of H_j, running over all non-equivalent intersections. and humbert-intersections-level1.txt (226KB) Level 1 Humbert intersections - Factors of resultants of level 1 Humbert surfaces using the s_i model. SF[i][j] is the set of irreducible factors of the resultant of equations defining H_i and H_j.
