Comment(by cremona):
You are right. I changed the ordering explicitly at William's request, to
agree with what he is using for more general modular forms. But the rule
of the game is that after publishing tables I do not want to change all
the labels of all the curves with hindsight. So the database labelling is
"old".
Also in eclib src/g0n/newforms.cc you see
{{{
if((n1ds>1)&&(modulus<130000)) // reorder into old order
{
if(verbose)
{
cout<<"Reordering newforms into old order as N<130000"<<endl;
// cout<<"Before sorting:\n"; display();
}
sort(1);
if(verbose)
{
// cout<<"After sorting:\n"; display();
}
}}}
showing that the output of eclib itself uses old ordering for N<130,000
(only).
