Choose.choose_modEq_choose_mod_mul_choose_div

∀ {n k p : ℕ} [Fact (Nat.Prime p)], ↑(n.choose k) ≡ ↑((n % p).choose (k % p)) * ↑((n / p).choose (k / p)) [ZMOD ↑p]

For primes p, choose n k is congruent to choose (n % p) (k % p) * choose (n / p) (k / p) modulo p. Also see choose_modEq_choose_mod_mul_choose_div_nat for the version with MOD.
