This article is about higher-dimensional algebra and supercategories in generalized category theory, super-category theory, and also its extensions in metamathematics, and the latter groupoid can be considered as a special case of a category with all invertible arrows, or morphisms. Double groupoids are often used to capture information about geometrical objects such as higher-dimensional manifolds and were further developed towards applications in nonabelian algebraic topology
