  We make available some results about model theory cyclically ordered groups.
We start with a classification of complete theories of divisible abelian
cyclically ordered groups. Then we look at the cyclically ordered groups where
the only parametrically definable subsets are finite unions of singletons and
open intervals, and those where the definable subsets are finite union of
singletons and c-convex subsets, where being c-convex is the analogue of being
convex in the linearly ordered case.
