randomPureBinomialIdeal -- randomPureBinomialIdeal with binomials of given degrees

Synopsis

• Usage:

  I = randomPureBinomialIdeal(L,S)

• Inputs:
  • L, a list, or sequence of positive integers
  • S, a ring, Polynomial ring
• Outputs:
  • I, an ideal, generated by random pure binomials (that is, differences of monomials without coefficients) of the given degrees
