In this paper we consider spaces of GL(4, R)-Whittaker functions, which are special functions that arise in the study of GL(4, R) automorphic forms. Our main result is to determine explicitly the series expansion for a GL(4, R)-Whittaker function that is «fundamental,» in that it may be used to generate a basis for the space of all GL(4, R)-Whittaker functions of fixed eigenvalues. The series that we find in the case of GL(4, R) is particularly interesting in that its coefficients are not merely ratios of Gamma functions, as they are in the lower-rank cases. Rather, these coefficients are themselves certain seriesnamely, they are finite hypergeometric series of unit argument. We suspect that this is a fair indication of what will happen in the general case of GL(n, R)
