Roblox has no official specification defining each format, so their implementation is the only source to look to. However, parts of their implementation could be better.

A graded-commutative ring is a mildly noncommutative ring in which `x*y = (-1)**(x.deg()*y.deg())*y*x` for the right notion of degree. This ticket aims to implement ideals of graded-commutative ring…

Returns the degree of a homogeneous ideal.
EXAMPLES::
```
sage: R. = QQ[]
sage: I = R.ideal(x+y)
sage: I.degree()
1
sage: J = R.ideal(x^2+y)
sage: J.degree()
Traceback (most recent call last)

Returns the ideal of relations for Rees algebra of this ideal.
```
sage: R. = QQ[]
sage: I = R.ideal(x^3,x*y,y^2)
sage: I.blow_up_ideal()
Ideal (y*t1 - x*t2, x*t1^2 - t0*t2, x^2*t1 - y*t0, x^3*t2 -…

Hi guys
Do you have implementation for IDEAL bank (selecting bank, redirect and return redirect) such as for web?
Thanks
