I asked sage to execute the first example:
sage: R.<x,y> = QQ[]
sage: q = x^4 + y^4
sage: quartic = invariant_theory.binary_quartic(q); quartic
But received the following error:
Traceback (click to the left of this block for traceback)
...
NameError: name 'invariant_theory' is not defined
I have the newest version of sage installed. What's going wrong here?Fri, 08 Mar 2013 21:31:11 +0100https://ask.sagemath.org/question/9896/invariant_theory-package/Comment by John Palmieri for <p>I am trying to follow the tutorial on the invariant_theory package: <a href="http://www.sagemath.org/doc/reference/sage/rings/invariant_theory.html">http://www.sagemath.org/doc/reference...</a></p>

https://ask.sagemath.org/question/9896/invariant_theory-package/?comment=18080#post-id-18080Exactly what version of Sage do you have installed? You need 5.7 or later to use this feature.Sat, 09 Mar 2013 11:21:18 +0100https://ask.sagemath.org/question/9896/invariant_theory-package/?comment=18080#post-id-18080
