Recently, the Soviet mathematicians R. Ismagilov , E. Gluskin  and B. Kashin  have obtained some deep and surprising results on $n$-widths for Sobolev spaces in the mixed norm case. In this note, we will give a new and simpler proof of Gluskin's result and show its connection with a certain classical combinatorial problem.
