While I believe it is true that all symmetric positions are local maxima,
It is definitely NOT true that all local maxima are symmetric. As
a counterexample, consider that a repeated permutation is at a local
maximum 1/2 way through its period. So for example, the Idempotent
( r u -r -u )^6 is at a familiar but unsymmetric local maximum
halfway through.
