A bounded plane convex region symmetric about a lattice point and with area 
must contain at least three lattice
points in the interior. In 
dimensions, the theorem can be generalized to a region with
area 
, which must contain at least three lattice
points. The theorem can be derived from Blichfeldt's
theorem.
