Abstract: Abstract We now apply the insertion semiproduct construction of Chapter 10 to extend some of the results in Chapter 6 concerning quasi-bijective relation algebras. Recall that a relation algebra is said to be quasi-bijective relation if it is atomic and if each rectangle with atomic sides is above at most one non-bijective atom. A complete description of these algebras is given in Structure Theorem 6.10, and a consequence of the description is that quasi-bijective relation algebras are always completely representable (see Representation Theorem 6.11).
