    23 ;; This package implements BASIC OPERATIONS ON MONOMIALS
    24 ;;----------------------------------------------------------------
    25 ;; DATA STRUCTURES: Conceptually, monomials can be represented as lists:
    26 ;;
    27 ;;      monom:  (n1 n2 ... nk) where ni are non-negative integers
    28 ;;
    29 ;; However, lists may be implemented as other sequence types,
    30 ;; so the flexibility to change the representation should be
    31 ;; maintained in the code to use general operations on sequences
    32 ;; whenever possible. The optimization for the actual representation
    33 ;; should be left to declarations and the compiler.
    34 ;;----------------------------------------------------------------
    35 ;; EXAMPLES: Suppose that variables are x and y. Then
    36 ;;
    37 ;;      Monom x*y^2 ---> (1 2)
