A Few Equivalences of Wall-Sun-Sun Prime Conjecture
  In this paper, we prove a few lemmas concerning Fibonacci numbers modulo primes and provide a few statements that are equivalent to Wall-Sun-Sun Prime Conjecture. Further, we investigate the conjecture through heuristic arguments and propose a few additional conjectures for future research.
