Comment (by cremona):
Looking more carefully at the code (I am not embarrassed that I wrote it
but could not remember) I see that for j=0 and j=1728 the curve returned
is always a quadratic twist. So the "additionally" part of the ticket's
current description is incorrect.
If you agree with me on that (and a second opinion would be welcome!) then
that just leaves the first part which I can easily implement by adding one
line.
