[sage-support] inconsistent subobjects

2007-11-26 Thread Francis Clarke
Subgroups of abelian groups: sage: G. = AbelianGroup(2) sage: A = G.subgroup([a]) sage: B = G.subgroup([b]) sage: A == B True Surely not! On the other hand for vector spaces: sage: W. = QQ^2 sage: U = W.subspace([u]) sage: V = W.subspace([v]) sage: U == V False As expected. -- Francis Clark
