## Abstract Let __G__ and __H__ be 2‐connected 2‐isomorphic graphs with __n__ nodes. Whitney's 2‐isomorphism theorem states that __G__ may be transformed to a graph __G__\* isomorphic to __H__ by repeated application of a simple operation, which we will term “switching”. We present a proof of Whitn
