Formal target: Corpus.OEIS141057.conjecture1
Conjecture: the supercongruences $a(n \cdot p^k) \equiv a(n \cdot p^{k-1}) \pmod{p^{3k}}$ hold for primes $p \ge 5$ and positive integers $n$ and $k$.
Exact formal statement
∀ (p k n : Nat),
Nat.Prime p →
LE.le.{0} 5 p →
LE.le.{0} 1 k →
LE.le.{0} 1 n →
(HPow.hPow.{0, 0, 0} (Nat.cast.{0} p) (HMul.hMul.{0, 0, 0} 3 k)).ModEq
(Nat.cast.{0} (Corpus.OEIS141057.a (HMul.hMul.{0, 0, 0} n (HPow.hPow.{0, 0, 0} p k))))
(Nat.cast.{0}
(Corpus.OEIS141057.a (HMul.hMul.{0, 0, 0} n (HPow.hPow.{0, 0, 0} p (HSub.hSub.{0, 0, 0} k 1)))))This target is a formal statement, not a proof of the problem.
