Abstract
Two new results are proved concerning polyhedra that arise as relaxations of systems of the form Ax=b, x≥0. One of these theorems is used to relate elementary vectors and blocking polyhedra. In particular, a canonical blocking pair that arises from elementary vectors is described; all blocking pairs arise as minors of blocking pairs of this type. It is noted that a similar relationship between elementary vectors and antiblocking polyhedra follows from the second relaxation theorem.
