I think so. It works as a "VMware virtual appliance", which you download here: http://sagemath.org/SAGEbin/microsoft_windows/ I believe vmware works fine in Vista, XP, 2000, and many other flavors of Windows. > Or it is better to use some Linux OS like Ubuntu or so. Actually, the SAGE "vmware appliance" mentioned above is just a minimal install of Ubuntu into a pre-made vmware machine, along with an install of Sage. > Is there an opportunity to use in SAGE modules written in > FORTRAN? Yes, definitely. Using FORTRAN from Sage is well supported. I'm not saying it is trivial to learn how to do it, but the technology is very much there. You can even use FORTRAN directly in the Sage GUI. There are some examples here: http://sage.math.washington.edu/tmp/sage-2.8.9.rc1/devel/doc/overviews/numerical_sage/numerical_sage.pdf > A more concrete point: does SAGE have some special > routines to check isomorphisms of graphs? Yes, Sage does. We have our own new -- completely open source and optimized -- graph isomorphism tester, which is an implementation of the same algorithm as the one in Nauty. It can also compute automorphism groups of graphs. The implementation is due to Robert Miller (a graduate student at University of Washington).
