Let E be an infinite dimensional separable space and for e E and X a nonempty compact convex subset of E, let qX(e) be the metric antiprojection of e on X. Let n 2 be an arbitrary integer. It is shown that for a typical (in the sence of the Baire category) compact convex set X E the metric antiprojection qX(e) has cardinality at least n for every e in a dense subset of E.
