摘要
For each positive integer n and a continuum X, we will denote by F-n(X) the nt-symmetric product of X and by X-n the product of X with itself n times. In this paper we study finite graphs X such that X-n can be embedded in F-n(X). We also present a geometric model of the third symmetric product of a simple triod.
