A systematic permutation‐group approach for both the classification and description of the Feynman–Goldstone diagrams is presented. It allows us to “algebraize” the topological concepts and notions of many‐body diagrammatic techniques, for example, the connectivity and disconnectivity of diagrams, the automorphism of a diagram, etc.
