content: Attempts to use computers to manipulate symbols as well as numbers date from the mid-1950s, with programs first published in the mid-1960s. George E. Collins (1928-2017), a computer science professor at the University of Wisconsin, introduced the program PM (Polynomial Manipulation) in 1966 and a system of Fortran programs known as SAC-1 (Symbolic and Algebraic Calculation) beginning in 1967. The topologist Robert F. Riley (1935-2000) of Binghamon University in New York used this documentation for a later version of SAC-1 in his studies of the polynomials associated with knots and links. More specifically, this guide was written by George E. Collins and Stuart C. Schaller and published in 1976 by the Computer Sciences Department at Wisconsin as its Technical Report #269.
