And if the polynomial ring is in finitely many variables, you at least
stand a chance, and the reference I quoted is irrelevant, EXCEPT to show
that you do need to use this knowledge about the field,

Given that it claims to be about both research and education usage, I'm
forwarding this to the other relevant Google groups. Nice find!

Hopefully doing this correctly since not exactly a "question". Just wanted
to make sure this group new about this.

Thanks all.
Even better when I discovered the locals option, which enables control of
variable evaluation.

which preparses it's input while eval does not.

The problem is that you are using eval, but should be using sage_eval.
eval is a python command that uses python integers, rather than Sage
integers and rationals.
sage: eval("1/2")
0
sage: sage_eval("1/

Dear Keshav,
Thanks very much, that helps a lot and makes lots of sense now.
Using what you said, I was able to encode 'HAPPYNEWYEAR' using a 1-based
system (A=1, B=2, C=3,Z=26) by applying (i) a multiplicative cipher
with a=1,b=1 to change to a 1-based system (ii) then a multiplicative
