  Lindel\"of topological groups $G_1$ , $H_1$, $G_2$, $H_2$ are constructed in
such a way that the products of $G_1 \times H_1$ and $G_2 \times H_2$ are not
$\mathbb R$-factorizable groups and (1) the group $G_1 \times H_1$ is not
pseudo-$\aleph_1$-compact; (2) the group $G_2 \times H_2$ is a separable not
normal group and contains a discrete closed subset of the cardinality
continuum.
