    made more of the keywords be hyperlinked;

    made the pointer to the references be hyperlinked;

    and did some minor polishing of the formatting,

    such as extending hyperlinks over the full plural form of a term (which looks much better and works due to the magic of redirects),

    and such as replacing

      :
    

    with

      \colon
    

    in math-mode (since otherwise it comes out ugly, for some reason)

    FinRelFinRel can’t be isomorphic to Mat(Bool)Mat(Bool), since the latter is skeletal (and has countable many objects), but the former is not skeletal, and is usually large (eg in ZFC). So I’ve replaced the “isomorphic” by “equivalent”.
