Here we obtained some results on the values of the minimal polynomial of this number in modulo prime p. This results help in the calculation of the congruence subgroups of the Hecke groups which is an important problem in discrete group theory.eninfo:eu-repo/semantics/closedAccessMathematicsHecke groupsRoots of unityChebycheff polynomialsMinimal polynomialProceedings Paper0003022398000922-s2.0-818552032873753771389Mathematics, appliedHecke Groups; Modular Forms; Congruence Subgroups
