Hi,
I'm trying to run the following on the online sagenb server (
http://www.sagenb.org):
f = ModularForms(Gamma1(5),2).0
f*f
I am getting an error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "_sage_input_5.py", line 10, in <module>
exec compile(u'open("___code___.py","w").write("# -*- coding: utf-8 -*-\\n"
+ _support_.preparse_worksheet_cell(base64.b64decode("Zipm"),globals())+"\\n");
execfile(os.path.abspath("___code___.py"))
File "", line 1, in <module>

line 423, in character
raise ValueError, "Form is not an eigenvector for <%s>" % g
ValueError: Form is not an eigenvector for <2>
Am I doing something wrong?
Kind regards,
Nadim.
