    Added missing adjective “symmetric” to the second characterization of cartesian monoidal categories (thanks to dremodaris on MO).

    Added link to the MO question mentioned by Mike is #4.

    I want to check if anyone knows a reference for this claim about Robin Houston:

    The characterization of cartesian monoidal categories in terms of ee and Δ\Delta, apparently discovered by Robin Houston, is mentioned here:

    • John Baez, Universal algebra and diagrammatic reasoning, 2006. pdf

    and as of 2014, Nick Gurski plans to write up the proof in a paper on semicartesian monads.

    In the slides at the link I see no mention of Robin Houston at all. Do we have a source for this? Also, the “as of 2014” remark is wildly out-of-date. Any more on this, or should it be deleted?
