Subject: eja/euclidean_jordan_algebra.py: remove symmetry test that don't work.
X-Git-Url: https://gitweb.michael.orlitzky.com/?a=commitdiff_plain;h=03e10c604439fb14dfe7010e3d69b0340987c9cb;p=sage.d.git

eja/euclidean_jordan_algebra.py: remove symmetry test that don't work.

I don't know why, but the multiplication table of a commutative
algebra doesn't have to be symmetric. I'll think about this later.
In the meantime, don't crash about it.
