   Given two quotients, one of which quotients a container, and the
   other quotients the type in the container, we can write the
-  composition of those quotients. This becomes especially interesting
+  composition of those quotients. To compose two quotient theorems
+  we compose the relations with relation composition
+  and the abstraction and relation functions with function composition.
+  The @{term "Rep"} and @{term "Abs"} functions that we obtain are
+  the same as the ones created by in the aggregate functions and the
+  relation is the same as the one given by aggregate relations.
+  This becomes especially interesting
   when we compose the quotient with itself, as there is no simple
   intermediate step.
