The n-skeleton of a (2n + 2)-simplex does not embed in R2n. This well-known result is due (independently) to van Kampen, 1932, and Flores, 1933, who proved the case p = 2 of the following: Theorem. Let p be a prime, and let s and I be positive integers such that l(p 1) < p(s 1). Then, for any continuous map f from a (ps + p 2)dimensional simplex into R1, there must exist p points {x ' . . xp} lying in pairwise disjointfaces of dimensions < s 1 of this simplex, such that f(xl) = * (xp)
