We present evidence for the general conjecture that that $C(P)=d$ whenever $P(0^d)\ne P(1^d)$ and $P$ is left invariant by a transitive permutation group acting on its arguments. A non-constructive argument (not based on the construction of an ``oracle'') proves the generalized conjecture for $d$ a prime power. We use this result to prove the Aanderaa-Rosenberg conjecture by showing that at least $v^2/9$ entries of the adjacency matrix of a $v$-vertex undirected graph $G$ must be examined in the worst case to determine if $G$ has any given non-trivial monotone graph property. }, }
