Abstract
Elementary lift is a generalized splitting operation. Splitting of a binary gammoid need not be a gammoid. This paper finds forbidden minors for a binary gammoid whose elementary lift is a binary gammoid. We also find forbidden minors for a binary gammoid whose single element coextension is a binary gammoid.
