Abstract:We prove that a Hausdorff sequential topological group with a point-countable $k$-network is metrizable iff its sequential order is less than $omega _{1}$. In the non Hausdorff case metrizability may be replaced by $sigma $-locally finite base.

Keywords:Topological group   sequential space   sequential order   Fr'{e}chet space   $k$-network
