It's the max number of edges in a disconnected graph + 1.
So suppoose we have a maximal disconnected graph. Then each connected component must be a clique.
So answer = K_2003 + isolated vertex.

### Re: ONTC Final Exam

In p2 , 2^m-1 according to m makes a sequence - if m = 1 , then 2^m-1 = 1 . For m as 2 , 2^m-1 = 3 . For m as 3 , 2^m-1 = 7 . Let 2^m-1 = X . The sequence - Xn = 2*X(n-1) + 1 where X1 = 1 . In the whole sequence only when m = 1 , X divides n^2+1 . For ex : n^2+1 = 1, 2 (mod 3) etc . My proof is poor...
