- Let $τ$ be an uncountable cardinal. The notion of a \emph{$τ$-fine} topological group was introduced in 2021. More recently, H. Zhang et al. generalized this concept by defining pseudo-$τ$-fine topological groups to study certain factorization properties of continuous functions on topological groups. It is known that $τ$-fineness cannot coexist with precompactness in topological groups with uncountable character. In this paper, we investigate this problem further. We prove that, in topological groups with uncountable pseudocharacter, precompactness can coexist with pseudo-$τ$-fineness for some bounded $τ$ but pseudocompactness can never.
