It looks pretty close to the right-hand side of http://en.wikipedia.org/wiki/Meijer_G-function#Polynomial_cases. I'm afraid I'm not good enough with the notation to tell if the indices match up or not, though. There are some other forumlas on that page with sums of G-functions on the right-hand side as well.
