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_9, a Duflot regular element of degree 2
    2. c_8_135, a Duflot regular element of degree 8
    3. b_1_32 + b_1_2·b_1_3 + b_1_22 + b_1_1·b_1_3 + b_1_12 + b_1_0·b_1_3 + b_1_02, an element of degree 2
    4. b_1_32, an element of degree 2
  • The Raw Filter Degree Type of that HSOP is [-1, -1, 4, 8, 10].
  • The filter degree type of any filter regular HSOP is [-1, -2, -3, -4, -4].
