SkewCommutative

SkewCommutative -- name for an optional argument for monoids that specifies that monoid rings created from them will be skewcommutative.

The default value is false.

     i1 = R = ZZ[x,y,SkewCommutative=>true]
     
     o1 = R
     
     o1 : PolynomialRing
     
     i2 = x*y
     
     o2 = x y
     
     o2 : R
     
     i3 = y*x
     
     o3 = -x y
     
     o3 : R
