abstract = {We study the relation between a space $X$ satisfying certain generalized metric properties and its $n$-fold symmetric product $\mathcal \{F\}_n(X)$ satisfying the same properties. We prove that $X$ has a $\sigma $-$(P)$-property $cn$-network if and only if so does $\,\mathcal \{F\}_n(X)$. Moreover, if $\,X$ is regular then $X$ has a $\sigma $-$(P)$-property $ck$-network if and only if so does $\,\mathcal \{F\}_n(X)$. By these results, we obtain that $X$ is strict $\sigma $-space (strict $\aleph $-space) if and only if so is $\mathcal \{F\}_n(X)$.},
