Abstract. We consider linear homogeneous difference equations with ra-
tional-function coefficients. The search for solutions in the form of the m-
interlacing (1 m ord L, where L is a given operator) of finite sums of
hypergeometric sequences, plays an important role in the Hendriks­Singer
algorithm for constructing all Liouvillian solutions of L(y) = 0. We show
that Hendriks­Singer's procedure for finding solutions in the form of such
