Abstract
Let R be a ring, and let S be the injective hull of the right regular module RR. Suppose that S can be made into a ring with multiplication compatible with that of R. Osofsky, in 1964, asked if SS is necessarily injective. We construct examples giving a negative answer to this question, and even construct an infinite chain of such rings.
