multTableOneOne(...,Compact=>...) -- an optional argument for multTableOneOne that prints dots below the diagonal

Synopsis

• Usage:

  multTableOneOne A

• Inputs:
  • A, a ring, created with resLengthThreeAlg or resLengthThreeTorAlg
• Outputs:
  • a list, of the rows in the multiplication table; use netList to display it as a table

Description

The default value of Compact is false. Changing the value to true saves space by printing dots for the products $e_ie_j$ for $i>j$

i1 : Q = QQ[x,y,z];

i2 : A = resLengthThreeAlg res ideal (x^2,y^2,z^2)

o2 = A

o2 : QuotientRing

i3 : multTableOneOne (A, Compact => true)

o3 = {{ , e , e , e }, {e , 0, f , f }, {e , ., 0, f }, {e , ., ., 0}}
           1   2   3     1      1   2     2         3     3

o3 : List

i4 : netList multTableOneOne(A, Compact => true)
