    I gave functorial factorization its own little entry, for ease of pointing to the precise definition.

    This is for the moment just copied over from the corresponding paragraph at weak factorization system (where I have re-organized the sectzion outline slightly, for clarity). Also I added cross-links with some relevant entries.

    In a simplicial model category with small object argument. Can functorial factorization be simplicially functorial?

    Yes, because every simplicial set is cofibrant. See 4.3.8 in Hirschhorn’s book or 24.2 here.

    Thanks! I have added these pointers here.

    Removed references to wfs (not all functorial factorizations are wfs’s), moved the explicit definition into the definition section alongside the abstract definition, and added the equivalence to pointed endofunctors over cod.
