proposition: Proposition transportf_disp_mor2_struct_cospan {a₁ a₂ b₁ b₂ : A} {f f' : a₁ --> a₂} (p : f = f') {g g' : b₁ --> b₂} (q : g = g') {s₁ : struct_cospan a₁ b₁} {s₂ : struct_cospan a₂ b₂} (sq : struct_cospan_sqr f g s₁ s₂) : struct_cospan_sqr_ob_mor (transportf_disp_mor2 p q sq) = struct_cospan_sqr_ob_mor sq.
proof: Proof. induction p, q ; cbn. apply idpath. Qed.
