[sage-devel] sage-2.4-rc2

2007-03-24 Thread William Stein
I've posted a release candidate for sage-2.4 here: http://sage.math.washington.edu/home/was/tmp/rc/ It would be helpful if a few people would build this and, if that works, do a "make test", and let me know what happens. I will make an official release sometime on Sunday. Here's what's includ

(Partial) factorization (by trial division) of p-1 is in other to make use of CRT of discrete logarithms mod m where m | p-1. The index calculus algorithm requires a relations collection phase, and a linear algebra phase. The linear algebra phase just requires sparse linear algebra over F_2 to d

Sorry factoring p-1 for an 128 bit number p is of course not an issue. I was confuse. Michel --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, v

I tested the plain version. It computed the log of y=74854337848345720324273746248836352273 modulo p=241336555202451377063690009552755901639 (128bit) with base g=132937783468242454805077125996488454291 in 15704.5 (setup time) + 18681.4 seconds on a 1.6GHz laptop with 1Gb. (the answer is 4711
