Hi all, I created an unital associative free algebra
sage: F.<x,y>=FreeAlgebra(QQ, implementation='letterplace'). But for having a twisted ideal I=F*[x*y*x*y-x*y]*F in F, I have faced the following error: ArithmaticError : can only subtract the elements of the same degree. Am I in wrong place in sage? Also I want to define an infinite dimensional quotient algebra in non-commutative algebra F/I. Is there a way to define that in sage or other part of sage like Gp or Singular?
