O článku:
Let $(E,
ho)$ be a space of the set $E$ of all permutations
of positive integers furnished with the Fr'echet metric
$
ho$. In the paper a class of non-absolutely convergent
series otsmash{$sum^infty_{n=1} c(n)$} is given such that the set
$igl{x=(x_n): sum^infty_{n=1} c(x_n) ext{ converges}igr}subset E$ is an
$(x^{v^{-1}})$-$sigma$-porous set for each
$sum^infty_{n=1}c(n)$ of the above class.
