I installed VMware Player 2.5.2 on my windows xp machine and then run the VMware sage appliance. However, I was unable to log in using either notebook or sage as the sage login name. I then logged in using manage. The following are the interactions and message I got from the appliance. What was wr

Since no one has answered this, you might want to email John Palmieri (palmaieri at math dot washington dot edu) directly, since he is the author of the simplicial complex module in sage. -Marshall Hampton On Aug 10, 10:41 pm, Rafael Villarroel wrote: > Hello all, > > Under friendly advice by F
