Abstract
Several facts concerning transformations and summations of hypergeometric functions with integral parametric differences have been proven. A new summation formula complementing the well-known Karlsson–Minton summation formula has been established. A new three–term relation has been derived from the first Miller–Paris transformation. It is shown how the second Miller–Paris transformation can be obtained by induction from the Euler–Pfaff transformation, and a recursive formula for the representing polynomial is provided. An integral representation of Meijer's G-function, which underlies the second Miller–Paris transformation, has been established.

Keywords:
generalized hypergeometric function, summation formulas, hypergeometric identity, Miller–Paris transformations.
