Simultaneous identities of the golden ratio and Euler's identity, formally verified in Lean 4 over the known Mersenne prime exponents

We present a sustained study of a single object followed across representations, where the content lives in the equivalences between them. We prove and formally verify in Lean 4 that the golden ratio φ=(1+√5)/2 satisfies simultaneously twelve identities across five canonical stru...
