Query: Exceptional Discrete Mapping Class Group Orbits in Moduli Spaces   Let $M$ be a four-holed sphere and $\Gamma$ the mapping class group of $M$
fixing $\partial M$. The group $\Gamma$ acts on the space ${\mathcal
M}_{\mathcal B}(SU(2))$ of SU(2)-gauge equivalence classes of flat
SU(2)-connections on $M$ with fixed holonomy on $\partial M$. We give examples
of flat SU(2)-connections whose holonomy groups are dense in SU(2), but whose
$\Gamma$-orbits are discrete in ${\mathcal M}_{\mathcal B}(SU(2))$. This
phenomenon does not occur for surfaces with genus greater than zero.
