Efficient computation of terms of linear recurrence sequences of any order

Abstract

In this paper we give efficient algorithms for computing second-, third-, and fourth-order linear recurrences. We also present an algorithm scheme for computing terms with the indices N,,N+n1N,\ldots,N+n-1 of an nnth-order linear recurrence. Unlike Fiduccia's algorithm our approach uses certain formulas for modular polynomial squarings.
