I have a multiple summation involving gamma and hypergeometric functions and power series of several variables. I'd like to see if REDUCE can recognize the summations as some power series expansion of a known function. I have managed to do so with Mathematica for a simpler sum, but for these more complicated sums, Mathematica does not seem to be able to recognize anything out of them. If you are a user of the REDUCE software, and you're willing to spare a bit of your time, I'll send you a pdf file of 1-2 of the (many) summations I need to evaluate and you could tell me whatever answer REDUCE gives you. If it works I may end up purchasing it myself to complete this research project. Thanks for the help!
