The Sandwich Theorem is a fundamental one for Geography. It provides the limiting conditions concerning spatial partitioning. As a theorem it provides information concerning the existence of solutions but not analytical means for finding them. This paper provides geometrical inter- pretations of the nature of the Sandwich Theorem and its relationship to Geography and provides an algorithm and a complete program to achieve solutions. Also included is a translation of one work of Hugo Steinhaus. Author
