There are many results about the minimal polynomial of this algebraic number. Here we obtain the minimal polynomial of these numbers over the field of rationals by means of the better known Chebycheff polynomials and the Maple language.eninfo:eu-repo/semantics/closedAccessMathematicsPhysicsProceedings Paper0003106981000892-s2.0-848831056643713741479Mathematics, appliedPhysics, appliedHecke Groups; Modular Forms; Congruence Subgroups
