If a countable group G admits a non-discrete Hausdorff group topology, then the lattice of all group topologies of the group G admits:{ continuum c of non-discrete metrizable group topologies such that supf¿1; ¿2g is the discrete topology for any two of these topologies; { two to the power of continuum of coatoms in the lattice of all group topologies. |
