Elementary lift and single element coextension of a binary gammoid

AKCE International Journal of Graphs and Combinatorics
It is known that every binary elementary lift of a binary matroid is a matroid obtained by applying the splitting operation on that matroid. An elementary lift of a binary gammoid need not be a binary gammoid.
