proposition: Lemma KAOctaComm2 {x y z : Complex A} (f1 : Morphism x y) (f2 : Morphism y z) : # (ComplexHomotFunctor A) (MorphismComp (KAOctaMor2 f1 f2) (KAOctaMor3 f1 f2)) = # (ComplexHomotFunctor A) (MappingConeIn2 A (KAOctaMor1 f1 f2)).
proof: Proof. use ComplexHomotFunctor_rel_mor'. - exact (KAOctaComm2Homot f1 f2). - exact (KAOctaComm2Eq f1 f2). Qed.
