Streszczenie
We compute transitive cardinal coefficients of ideals on generalized Cantor spaces. In particular, we show that there exists a null set $A\subseteq 2^{\omega _1^{\ }}$ such that for every null set $B\subseteq 2^{\omega _1^{\ }}$ we can find $x\in 2^{\omega _1^{\ }}$ such that $A\cup (A+x)$ cannot be covered by any translation of $B$.
