>From what I know of the algorithm used -- and one should ask the pari list to be certain -- it computed h*R (class number times regulator) analytically and then, by factoring primes up to some bound, obtains lower bounds on both h and R selarately until the product is within a factor <2 of the known product. If that is the algirithm in use here, then it could mean that when the unit generators are not certain then neither is the class number. > > > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to sage-support+unsubscr...@googlegroups.com. > To post to this group, send email to sage-support@googlegroups.com. > Visit this group at https://groups.google.com/group/sage-support. > For more options, visit https://groups.google.com/d/optout. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
