Title:  Fat, symmetric, irrational Cantor sets. (In English)

Review:  For 0 < \alpha \leq 1 let C\alpha be the Cantor set in [0,1] obtained by the familiar process of removing middle intervals of length \alpha/3, \alpha/32 etc. It is proved that the set of \alpha in (0,1] for which C\alpha consists only of irrational numbers is residual in [0,1].
