  "body": "Roberts and Vivaldi's 2005 paper studies time-reversal symmetry in polynomial automorphisms over finite fields, including area-preserving Hénon maps and their cycle statistics. Their 2009 paper develops the associated random-involution model and its universal limiting distribution.\n\nThe displayed reversing identity puts this problem in that setting. The two papers discuss asymptotic behavior and computations at other moduli. The focused formula, title, and citation audit found no published complete decomposition for \\(y^2+1-x\\) at \\(p=65537\\). This fixture therefore records 294,672 as a certified lower bound and leaves the finite maximum unresolved.",
