% Having just tried to do some simple things, I've found that there are maths
% symbols missing. Here they are, in all their glory:

% A few esoteric new operator names are supplied.

% I think |\lcm| ought to be self-explanatory. The |\dom| and |\ran|
% operators pick out the domain and range of a function, respectively; thus,

% Now we need to do some more calculating (don't you hate it?). As far as
% Appendix~G is concerned, $\theta=h(y)=0$, because we want no rule over the
