WebThere is no problem with "duplicate elements". It's just that the set { { a }, { a } } is equal to the set { { a } } by the Axiom of Extension, which says that two sets A and B are equal if and only if for every x, x ∈ A ↔ x ∈ B. The ordered pair ( a, a), as a set, is a set which can be written as.
