<Index Key=
"Circle package">&Circle; package</Index>
The &GAP;4 package &Circle; extends the &GAP; functionality
for computations in adjoint groups of associative rings.
It provides functionality to construct circle objects that will
respect the circle multiplication <M> r \cdot s = r + s + rs </M>,
and to compute adjoint semigroups and adjoint groups of finite rings.
Also it may serve as an example of extending the &GAP; system with
new multiplicative objects.
