Data used for Benson′s test

  • Benson′s completion test succeeded in degree 12.
  • The completion test was perfect: It applied in the last degree in which a generator or relation was found.
  • The following is a filter regular homogeneous system of parameters:
    1. c_2_7, a Duflot regular element of degree 2
    2. c_4_22, a Duflot regular element of degree 4
    3. c_4_23, a Duflot regular element of degree 4
    4. b_1_22 + b_1_12, an element of degree 2
  • The Raw Filter Degree Type of that HSOP is [-1, -1, -1, 5, 8].
  • The filter degree type of any filter regular HSOP is [-1, -2, -3, -4, -4].
