PARI package GALPOL 3.0 released |
Dear PARI users, Igor Schein and me have just released GALPOL v3.0, a database of polynomials defining Galois extensions of the rationals representing all abstract groups of order up to 129, for all possible signatures, (7087 polynomials) see <http://pari.math.u-bordeaux.fr/galpol/>. For reference galpol 2.0 included 2429 polynomials for all groups of order up to 127. This database is available as a PARI package "galpol" from <http://pari.math.u-bordeaux.fr/download.html> Once installed, it can be accessed under GP using galoisgetpol. ? P=galoisgetpol(8,3,1); ? G=galoisinit(P[1],P[2]); ? galoisidentify(G) %6 = [8,3] ? polsturm(P[1]) %7 = 8 Note that some polynomials are different between galpol v2.0 and galpol v3.0. Cheers, Bill
