Hi Simon, Still trying to understand what you wrote. Paraphrasing your example, Someone asserts that a collection C2 is derived from collection C1 by removing e from C1 You claim that C2 is not necessarily derived from e, or do you claim that C2 is never derived from e, Is it a correct analogy? which claim are you making?
