proposition: Lemma interval_cartesian_cubical_sets_dec_eq : ∏ (n : cartesian_cube_category), isdeceq ((I : functor _ _) n : hSet).
proof: Proof. intro n. use isdeceqweqb. - exact (stn ((n+2) * 1)). - use weqcomp. + exact ((stn 1) → (stn (n+2))). + apply weqffun, weqfromcoprodofstn. + apply weqfromfunstntostn. - apply isdeceqstn. Defined.
