[Abstract-pdf]
We construct a locally compact group $G$ and a closed subgroup $H$ such that such that the quotient space $G/H$ is connected and has weight $w(G/H)=2^{\aleph_0}$ but fails to contain a cube $\I^{w(G/H)}$ of the same weight. This proves as incorrect an assertion made in Theorem 4.2 of K. H. Hofmann and S. A. Morris: Transitive actions of compact groups and topological dimension, J. of Algebra {\boldface 234} (2000), 454--479.
Keywords: Homogeneous spaces of locally compact groups, Tychonoff cube, dimension.
