We classify the Bore1 ideals I on the set of natural numbers N for which p(N)/1 can be Bore1 embedded into the orbit space of a Bore1 action of the infinite symmetric group. As a consequence we show that certain Bore1 ideals I, including the FrCchet ideal, are completely characterized by the "Bore1
