Abstract
We give a lower bound of \Omega\Gamma f bd=2c ) for the
number of vertices of a d­dimensional poly­
tope with f facets which can appear on the
outer boundary of a projection to any di­
mension 2 Ÿ k ! d. By duality, this implies
a lower bound of \Omega\Gamma n bd=2c ) for the num­
ber of facets in a k­dimensional slice of a
