Mar 11, 2017 at 18:56 comment added Minimus Heximus yes exactly I'm looking for a solvable minimal topologically simple group. if any. @TarasBanakh
Mar 11, 2017 at 17:11 comment added Taras Banakh Oh, sorry, I did not notice that you are interested in solvable groups. Then you need to find a minimal solvable group $G$ in which every normal closed subgroup is either trivial or $G$? So, it looks like topologically simple.
Mar 10, 2017 at 19:25 comment added Minimus Heximus I remember symmetric groups larger than $S_4$ are not solvable. @TarasBanakh
Mar 9, 2017 at 7:48 comment added Taras Banakh It seems that for every cardinal $\kappa$ the group $Sym(\kappa)$ of permutations of $\kappa$ endowed with the topology of pointwise convergence is minimal and admits no weaker (Hausdorff) group topology. On the other hand, each topological group carries the (non-Hausdorff) anti-discrete topology. More information on the minimality of $Sym(\kappa)$ can be found in arxiv.org/pdf/1201.0087.pdf
