Let $$U = \{ 1,2,3\} $$. Let 2$$^U$$ denote the powerset of U. Consider an undirected graph G whose vertex set is 2$$^U$$. For any $$A,B \in {2^U},(A,B)$$ is an edge in G if and only if (i) $$A \ne B$$, and (ii) either $$A \supseteq B$$ or $$B \supseteq A$$. For any vertex A in G, the set of all possible orderings in which the vertices of G can be visited in a Breadth First Search (BFS) starting from A is denoted by B(A).

If $$\phi$$ denotes the empty set, then the cardinality of B($$\phi$$) is ___________
