  We report results of a nine-year monitoring effort on the unusual classical
Be with a robotic ground-based (APT) B,V-filtered telescope as well as
simultaneous observations in 2004 November with this instrument and the RXTE
(X-ray) telescope. Our observations disclosed no correlated optical response to
the rapid X-ray flares in this star, nor did the star show any sustained flux
changes during the course of either of the two monitored nights in either
wavelength regime. Our optical light curves reveal that gamma Cas undergoes
\~3%-amplitude cycles with lengths of 60--90 days. Over the nine days we
monitored the star with the RXTE, the X-ray flux varied in phase with its
optical cycle and with an amplitude predicted from correlated optical/X-ray
data from an earlier paper. The amplitudes of the V magnitude cycles are
30--40% larger than the B amplitudes, suggesting the seat of the cycles is
circumstellar. The cycle lengths constantly change and can damp or grow on
timescales as short as 13 days. We have also discovered a coherent period of
1.21581 +/-0.00002 days in all our data, which is consistent only with
rotation. The full amplitude of this variation is 0.0060 in both filters. The
derived waveform, somewhat surprisingly, is almost sawtooth in shape. This
variation probably originates on the star's surface. This circumstance hints at
the existence of a strong magnetic field with a complex topology and an
associated heterogeneous surface composition.
