Popis:	It is shown that for any finitely generated subgroups H and K of a free group F, and for any element g in F the double coset HgK is closed in the profinite topology of F. Comment: This paper was written many years ago, but has never been published. The main theorem of the paper has been reproved and improved many times, however, the argument presented here has never been reproduced. It is extremely short and elegant, and the paper is only 2 pages long
