That would be true if the license was legally enforceable, which I
very much doubt it is.

Two technical solutions:
1) have 'make' download the database.
2) Before we make each release, dump a few gigabytes onto the OEIS

In NumberField_absolute._coerce_map_from_, an
EmbeddedNumberFieldMorphism is constructed. The optional argument
(namely the ambient field) is constructed, but it was forgotten to

OK, I found the lack of evaluation on .
On a "FRESH" system when sage notebook() is entered
on the terminal screen a requester pops up asking for
a new password and VERY SOON after that
the browser window overlays it.
It is easy to miss the new password requester,
obviously I did on Friday.

Hi,
the function sloane_find seems to be broken after the recent updates
to The online encyclopedia of integer sequences, oies.org. For example
sloane_find([1,2,3,4,5,6])
does not find anything in the database. The oies has also taken down

I might be wrong, since coercion still looks "magic" like me. But it

I think I am out of my depth already, but I just wanted to make sure
that you knew of the composite_fields() method for number fields. In

Despite my earlier comment I am not proposing automatic coercion
between isomorphic number fields since there is (often, not always!)
more than one isomorphism.
Surely a number field + embedding is a richer structure than an
abstract number field, so the coercion should go from the former to
