    Are you asking for a reference on rational numbers?

    In any case, the entry should indeed give some textbook references. For the moment I have added pointer to the Wikipedia article, which lists references.

  5. adding definition of rational numbers as a higher inductive type in homotopy type theory from the HoTT book.

    There needs to be at least a line like: “Discussion in homotopy type theory…” and then there should also a pointer to page and verse in the book. Like this:
