# SageMath code for working with p-adic field 2.2.5.8a1.1. # Define the p-adic field: Prec = 100 # Default precision of 100 Q2 = Qp(2, Prec); x = polygen(QQ) L. = Q2.extension(x^2 + x + 1) K. = L.extension(x^5 + 2) # Defining polynomial: K.defining_polynomial() # Base field Qp: K.base() # Degree over Qp: K.absolute_degree() # Ramification index: K.absolute_e() # Residue field degree (Inertia degree): K.absolute_f() # Maximal unramified subextension: K.maximal_unramified_subextension() # Roots of unity: len(K.roots_of_unity())
