I meant that the sentence "Mick posted my idea of tetration generating all residues mod p" suggests a conjecture, but maybe I was wrong about its attribution, since the MSE thread tetration primitive root q mod p is by Mick himself.
Let \(G(n)\) be a generic reverse-concatenated sequence. If \(G(1) \notin \{2, 3, 7\}\), then \(^{G(n)}G(n) \pmod {10^d}≡^{G({n+1})}G({n+1}) \pmod {10^d}\), \(\forall n \in \mathbb{N}-\{0\}\)
