An affine subset of V is a subset of V that can be expressed as the translation of a subspace of V, View the full answer.

Web, the difference is that a strict subset cannot be the same set, that is, it cannot contain all of the elements that the other set does. Or in other words, a strict subset must be smaller, while a subset can be the same size.
