proposition: Lemma triviality_isomorphism_compute (G:gr) : triviality_isomorphism (trivialTorsor G) (unel G) = idActionIso (trivialTorsor G).
proof: Proof. apply subtypePath_prop. apply subtypePath. { intros X. apply isapropisweq. } apply funextsec; intros g. change (op g (unel _) = g). apply runax. Defined.
