Abstract
A finite oscillator dictionary which has important applications in sequences designs and the compressive sensing was introduced by Gurevich, Hadani, and Sochen in [Citation3]. In this paper, closed formulae of the finite split oscillator dictionary π s are revisited by a simple proof, the structure of nonsplit tori of the group SL(2, π½ p ) is studied, and an explicit algorithm for computing the finite nonsplit oscillator dictionary π ns is described.
