All the data that define the ambient space, the base ring, etc goes into the Parent. The element refers to the parent for constant data. Or, by analogy: Element : Parent Polynomial : PolynomialRing Hyperplane : HyperplaneArrangement There isn't really a simple introduction, but http://www.sagemath.org/doc/thematic_tutorials/coercion_and_categories.html spells out all the details. I don't really see a need for another affine space. It would be very confusing to present the user with multiple affine space implementations. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
