   Format: MarkdownItexIt's not the most palatable proposition in the world. Someone should one day break down such propositions into more digestible components. The [[salamander lemma]] was apparently introduced as a tool for simplifying such homological algebra demonstrations; would this be the case here I wonder?

   Format: MarkdownItexYes, I was thinking, too, that one should try to include in the page on the braid lemma a proof via the Salamander lemma.
