##### The maximum degree of a vertex in G is?

The 2n2n vertices of a graph G corresponds to all subsets of a set of size nn, for n≥6n≥6. Two vertices of G are adjacent if and only if the corresponding sets intersect in exactly two elements.

The maximum degree of a vertex in G is:

- (n/22)2n/2(n/22)2n/2
- 2n−22n−2
- 2n−3×32n−3×3
- 2n−1
