Statement

forall (A : Vec), forall (B : Vec), forall (P : Prop), forall (mk : forall (forward : forall (h : @Eq.{1} RingElem (dist A B) zero), @Eq.{1} Vec A B), forall (backward : forall (h : @Eq.{1} Vec A B), @Eq.{1} RingElem (dist A B) zero), P), P

Proof term

fun A => fun B => fun P => fun mk => mk (fun (h : @Eq.{1} RingElem (dist A B) zero) => @Vec.rec.{0} (fun (x : Vec) => @Eq.{1} Vec x B) (@Vec.rec.{0} (fun (y : Vec) => @Eq.{1} Vec Vec.unit y) (@Eq.refl.{1} Vec Vec.unit) B) A) (fun (h : @Eq.{1} Vec A B) => @Eq.refl.{1} RingElem (dist A B))
