It was proved in [HM] that each topological group (G,·,τ) may be embedded into a connected topological group (Ĝ,•,τ̂). In fact, two methods of introducing τ̂ were given. In this note we show relations between them.

We describe the finite group actions, up to equivalence, which can act on the orbifold $\Sigma (2,2,2)$, and their quotient types. This is then used to consider actions on prism manifolds $M(b,d)$ which preserve a longitudinal fibering, but do not leave any Heegaard Klein bottle invariant. If $\varphi :G\to \text{Homeo}\left(M\right(b,d\left)\right)$ is such an action, we show that $M(b,d)=M(b,2)$ and $M(b,2)/\varphi$ fibers over a certain collection of 2-orbifolds with positive Euler characteristic which are covered by $\Sigma (2,2,2)$. For the standard actions, we compute the fundamental group of $M(b,2)/\varphi$ and indicate when...
