Abstract

We characterize those symmetric d-lenses which are representable as cospans of d-lenses. Such a symmetric d-lens must have unique corrs per pair of objects and satisfy two other technical conditions. When the d-lens is also "least change" then the corresponding cospan consists of c-lenses.
