Using sage 9.7 and 10.3 (on an oldish iMac), I ran into some puzzling results, of which the following are minimal examples:
#1: sage: 4.is_square() True sage: 4.is_squarefree() False #2: sage: f=x^2-3 sage: K.<a>=NumberField(f) sage: OK=K.maximal_order() sage: v=OK.random_element() sage: v 2*a + 1 sage: v==v.conjugate() True #1 I don’t get (and it seems to contradict the “?” doc); while #2 may be a misunderstanding on my part. Thoughts? Pointers? Thanks, for any help. Justin -- Justin C.
