All right, so we identify the vertex set of g.
00:03
So the set as, which is just a set, contains five elements.
00:14
The set of all two element subsets would be, well, it would be one, two, one, three, one, three, one, five, and then two, three, four, two, five, and then three, four, three, five, and three, five, and four, five, and four, five.
00:35
Subsets.
00:37
So the vertex set of g contains those 10 subsets.
00:42
And then we define the adjacency in g.
00:44
So two vertices in g, which corresponds to the two elements subsets of s are adjacent if the subsets are disjoint.
00:54
So for example, we have that one, two.
01:05
These are going to be adjacent because they do not share any elements...
