	It does include reciprocal ratios, and assumes octave equivalence. Of course it would be trivial to extend it to a function of the equivalence interval so that tritaves could be allowed to flourish, and then your proposal would be with the trivial interval of equivalence, 1.

== Arbitrary definition? ==
This definition of a diamond seems arbitrary to me. It assumes octave equivalence and does not include reciprocal ratios, except in the sense that they are reduced to within an octave (so 1/5 becomes 8/5).

A more sensible definition would be the one used by Partch, and the one hinted at by Woolhouse. Hence, diamond({1, 3, 5}) would be {1/1, 3/1, 5/1, 1/3, 1/5, 5/3, 3/5}.

You could also simply define another function, in my opinion a much less useful one, as the set of all ratios. Where does Partch do this, and what should it be called?

It's what people have been calling the "q-limit diamond" for some time now, if you imput the odd integers up to q. And Wikipedia seems to think it's what Partch meant:
