Modular Inverses
This is a visual map of multiplicative inverses modulo . The integers from to are placed clockwise on a circular number line with at the top. Two integers that are inverses modulo are connected by an arrow. An integer that is its own inverse is marked by a colored dot. Those integers that have no inverse modulo are not marked.
