| Abstract: | A set X of boundary points of a (possibly unbounded) convex body K Ed illuminating K from within is called primitive if no proper subset of X still illuminates K from within. We prove that for such a primitive set X of an unbounded, convex set KEd (distinct from a cone) one has  X=2 if d=2, X 6 if d=3, and that there is no upper bound for X if d 4. |
