It is shown that for any directed quasi-ordered set (Q, ~<), there is a minimal ordinal number h such that every cofinal subset of Q contains a cofinal subset which is the 0-th class original set of a pure h-th class chain of Q. A special case of our results gives necessary and sufficient conditions

Minkowski space M d =(R d , || ||) is just R d with distances measured using a norm || ||. A norm || || is completely determined by its unit ball {x Β₯ R d | ||x|| [ 1} which is a centrally symmetric convex body of the d-dimensional Euclidean space E d . In this note we give upper bounds for the maxi
