โฆ Synopsis
Given a sample with replacement from a finite set ~, we show simply how to generate a maximal sequence of functions of the sample, all uniform on ~/, such that these functions are pairwise independent. We also consider the problem of generating a sequence of k-wise independent functions of the sample. To this end we set up a geometrical framework in which this problem is intimately related to that of finding, in a projective geometry of dimension r, a set of points such that no one subset with k points belongs to a hyperplane of dimension k -1.

A commonly used uniform random-number generator is examined in light of a genetic-simulation problem. Although this generator is often useful, it proves defective in this case. The author suggests that any proposed generator be checked for the properties needed by the simulation problem at hand.
