The Gross-Koblitz formula and a formula of Diamond are used to prove the congruence A=(1+((2 p-1 -1)/2)× 2a-(p/2a))(mod p 2 ) (p a prime number ≡ 1 (mod 4), p = a 2 + b 2 (a, b , ∈Z, a≡ 1 (mod 4))), proposed by F. Beukers which refines the well-known congruence A ≡ 2a (mod p) for the binomial coefficient A=((p-1)/2 (p-1)/4).
