Thank you very much! This may have worked. When first started, sage complained about not have the folder "spkg". In fact, it did not and I just added the older one from 3.4. I hope that's OK. armand On May 2, 3:08 pm, curious wrote: > This problem is just that the folder sage in the dmg cannot

This problem is just that the folder sage in the dmg cannot be copied. However, the contents of the folder _can_ be copied, so the solution is to create a folder somewhere on the machine hard disk (or an external disk) and copy the contents of the folder sage on the dmg to the new folder. David G

When an elliptic curve is created the code in the __init__ function in ell_generic.py (lines 164-5) do cause a multivariate polynomial ring to be created. In this case it's a new ring each time as the base field is always a new field. The reason this is done is that the elliptic curve class deri
