Abstract

In this paper, we prove that for any odd prime pp and for any pp-integer α\alpha ,we have (αp1p1)1α(α1)(α2α1)pk=1p11k+α2(α1)2p21i<jp11ij (modpm) \binom{\alpha p-1}{p-1}\equiv 1-\alpha (\alpha -1)(\alpha ^{2}-\alpha -1)p\sum_{k=1}^{p-1}\frac{1}{k}+\alpha ^{2} (\alpha-1)^{2}p^{2}\sum_{1\leq i<j\leq p-1}\frac{1}{ij} \ \pmod{p^{m}}, where m=7m=7 if p7p\neq 7 and m=6m=6 if p=7p=7. this congruence generalizes the congruences of Wolstenholme, Morley, Glaisher, Carlitz, McIntosh, Tauraso and Me\v{s}trovi\'c. It allows one to rediscover the congruences of Glaisher, Carlitz and Zhao in a simple way
