    I have added a pointer to magma in the first line (this would deserve to be added in any number of your recent additions, I’d think).

    There was a mentioning of “possibly empty group” at heap (here) and I have now cross-linked the two.

    By the way, since these “possibly empty” algebraic structures are not really standard concepts, as far as I am aware, could you add a line to orient the reader? I.e. pointing out why one would want the notion and who, if anyone, brought this up.
