    I have fixed the broken intended hyperlinks and added hyperlinks to a bunch of further keywords. Added TOC, floating topic context and plural redirect.

    Finally, bring pedantic, I changed the lead-in from

    A premodel category is a relaxation of the notion of a model category.

    to

    The notion of a premodel category is a relaxation of the notion of a model category.

    obtained by composing elements of AC with those of AF, is closed under the 2-out-of-3 property.
