WebSep 1, 2024 · That means you need to remove at least n 2 edges from the complete graph. If you do this by pairing the vertices, you get a complete graph minus a perfect matching. That graph is Eulerian, and (because n is big enough) still has 2 different Hamiltonian cycles). So the answer here is ( n 2) − n 2 = n ( n − 2) 2.
