    I have fixed the code in the first sentence. (There was a missing closing square bracket, and spurious whitespace within hyperlink syntax.)

    The following line seems to have been a message to the nLab community, so it’s best to have it here on the nForum. You wrote:

    Seems like hylomorphism is not around. Thanks so much for the amazing wiki!

    regarding comment 3

    that statement was added by the original creator of the article, Aistis Raulinaitis: https://ncatlab.org/nlab/revision/catamorphism/1

  3. Added the commuting diagram for catamorphisms. (Is there a way to get \llparenthesis \rrparenthesis? e.g. ⦇φ⦈ for denoting cata φ.)
