last line has an unprintable character (after '))').
If I save it (from a news-reader slrn pointed at the corresponding
gmane.org newsgroup)
this line looks as
float(G2[1].norm() - G[1].norm()) =A0> 0
If I save the file from the editor's reply, edit it and load into sSage,
it produces a syntax error
File "<string>", line 6
float(G2[_sage_const_1 ].norm() - G[_sage_const_1 ].norm()) >
_sage_const_0
^
SyntaxError: invalid syntax
but it could well be that this character got mangled on its way...
Best,
Dima
