Hello, In Sage 7.2 I get the following error:
R.<x> = PolynomialRing(QQ) pol_rep = [1, -12, 70, -264, 757, -1872, 4258, -8796, 15922, -24900, 33886, -40608, 43117, -40608, 33886, -24900, 15922, -8796, 4258, -1872, 757, -264, 70, -12, 1] K.<r> = NumberField(R(pol_rep)) print K.subfield(K(1)) [...] ValueError: 1 is not a root of the defining polynomial of Number Field in r0 with defining polynomial x Replace the last line by print K.subfield(K(0)) and I get [...] SignalError: Segmentation fault Replace pol_rep by [1, 1, 0, 1] and everything is fine though.
