👉 Meriquinoidal is a type of mathematical expression used in graph theory to describe an undirected connected graph. It can be defined as follows: 1. A directed graph G with n vertices (where n > 2) and m edges is called a "meriquinoid" if it satisfies the following conditions: - The number of incoming edges from each vertex is equal to its degree. - The number of outgoing edges from each vertex is also equal to its degree.
