Next: A Linear Algebra Point Up: Demonstration of a Perfect Previous: Case 7: Weight =

Case 8: Weight = 7

This is the whole plane, a codeword. Removing a point is not a codeword.

Thus these geomtric codewords form disjoint spheres of radius 1 that cover all weights of possible vectors from V. Hence this is a perfect code.
