Re: bigomega?

[zak seidov <zakseidov@yahoo.com>]

Dear all,
thanks for your help
(via the list and personal messages).
Unfortunately, with my knowledge (ignorance) of PARI
I could only use advice by Kurt Foster 
suggesting to rewrite slightly "my" code.
As a result, I'm now running b's ~ 4-5 * 10^9 with no complaining (yet). 
Thanks again,
Zak
