View on Github →refactor(logic/equiv/basic): remove fin_equiv_subtype
(#14603)
The types fin n
and {m // m < n}
are definitionally equal, so it doesn't make sense to have a dedicated equivalence between them (other than equiv.refl
). We remove this equivalence and golf the places where it was used.
