    The page split coequalizer said that the canonical presentation of an Eilenberg–Moore algebra is a split coequalizer in the category of algebras. I don’t think that’s right – if I recall correctly it’s reflexive there, but in general not split until you forget down to the underlying category. So I changed the page.

    This page had no references. I have now added pointer to:

    Am adding pointer to MacLane’s section VI also to a bunch of entries on categorical algebra, where it had all been missing.

    Are there split pushouts as well than?

    Amended the diagram for the algebra so that it matches the split coequaliser diagram.
