buildERing -- creates a ring to be used with other functions in the EquivariantGB package

Synopsis

Description

For now the monomial order on R is always Lex, with variables ordered from the last block to the first, with larger indices before smaller indices. For blocks with multiple indices the first index is most significant, followed by the second, etc.

i1 : R = buildERing({symbol y, symbol x}, {2,1}, QQ, 2)

o1 = R

o1 : PolynomialRing
i2 : vars R

o2 = | y_(1,1) y_(1,0) y_(0,1) y_(0,0) x_1 x_0 |

             1       6
o2 : Matrix R  <--- R
i3 : coefficientRing R

o3 = QQ

o3 : Ring
