Comment #1 on issue 2083 by [email protected]: Geometric Algebra and the
LaTeX Printer

I don't know if it's correct but the following changes in
sympy/galgebra/latex_ex.py file works for me (use at your own risk) It also
fixes an issue if the base is a symbol before XYZW in alphabetical order
(like E).

< ibase = 0

ibase = 0
for base in grade:
if base != 0:
if igrade > 0:
tmp = Symbol('AAAA')

base_str = base_str.replace('AAAA','')
