2013-01-26 00:23:53 +0100 asked a question How do I find a presentation for classical matrix groups like PGL(2,q)?

I know I can just take the group and do ".gens()", and that'll give me a list of generators, but is there a way to find the relations on them?

Also, is there a way to compute generators for kernels of group homomorphisms?

so there's no way to actually make the window larger?

thanks, that worked!

Hello there! I had the same problem as you, so after trying a few times with some random or typical user/password words, I have a possible answer you can try:

Username: admin

Password: sage

Hope it helps you, goodbye!

2013-01-06 14:22:43 +0100 commented question How do I sign in to my sage localhost notebook?

Also, when I book up the sage appliance va the Oracle VM VirtualBox Manager, if I don't do anything it leads me eventually to a large black console without any text (no blinking cursor, nothing). From http://wiki.sagemath.org/SageAppliance it seems that I should be seeing the sage notebook in that console, which I am not. Any ideas why this might be the case?

2013-01-06 14:18:01 +0100 asked a question what's the difference between the "sage" folder and "sage-5.5" ?

A couple questions -

I had last year installed an earlier version of sage. I attempted to delete it by deleting the contents of the folder C:\Users\wchen\VirtualBox VMs\

(I'm using windows 7)

Then I also uninstalled the VirtualBox VM via the control panel, and then reinstalled both via the instructions on http://wiki.sagemath.org/SageAppliance

Now after logging into the sage vm using the username/password "sage"/"sage", in the linux console under the path /home/sage, I see two folders, called "sage" and "sage-5.5". The former is highlighted light blue, whereas the latter is dark blue.

As far as I can tell, they both have exactly the same contents, and in particular each contains an executable called "sage".

What is the difference between the two?

thanks,

2013-01-06 14:06:42 +0100 asked a question How do I sign in to my sage localhost notebook?

After starting the virtualbox console by clicking "Start" in the Oracle VM Virtualbox Manager, and then entering "notebook()" once I've logged into sage via the username/pw "sage"/"sage", I am then able to open my browser to localhost:8000.

However, it then prompts me to sign in via a username and password.

I've tried using sage/sage, my local machine username/password, my google username/password, all to no avail. Each time it says that "Username is not in the system".

Any ideas?

After starting sage-5.5 by clicking "Start" in the Oracle VM VirtualBox Manager, a console opens up and appears to boot into some form of Linux.

However, there is no ability to scroll, and resizing the window does not change the size of the text buffer (the black area where the console is displayed is remains the same size and is just centered within the larger window).
