👉 In mathematics, a dyarchy is a type of network structure in which there are two or more nodes connected by multiple directed edges. In other words, it is a type of directed graph with an additional edge connecting each pair of nodes. A dyarchy can be defined as follows: - A dyarchy consists of two nodes, X and Y, that are connected by a single directed edge. - The number of nodes in the dyarchy is equal to 2. - There is no edge between
