Query: Regular Matroids with Graphic Cocircuits   We introduce the notion of graphic cocircuits and show that a large class of
regular matroids with graphic cocircuits belongs to the class of signed-graphic
matroids. Moreover, we provide an algorithm which determines whether a
cographic matroid with graphic cocircuits is signed-graphic or not.
