  Exton [Ganita 54(2003)13-15] obtained numerous new quadratic transformations
involving hypergeometric functions of order two and of higher order by applying
various known classical summation theorems to a general transformation formula
based on the Bailey transformation. We obtain the generalization of one of the
Exton quadratic transformations. The results are derived with the help of a
generalization of Dixon's summation theorem for the series ${}_3F_2$ obtained
earlier by Lavoie {\em et al}. Several interesting known as well as new special
cases and limiting cases are also given.
