Sorry for not being clear.
I meant I used geng —help.
Apparently, the equal divide doesn’t help in my example case.
Where is this geng.c file? If I modify geng.c, how should I build geng?

It would help if you gave some context for this. I'm guessing that most

And a new kernel is created for each interact cell. Right? This seems to
Saw this in the document:
res/mod : only generate subset res out of subsets 0..mod-1
How is the output divided?
I tried with : ../sage-8.6/local/bin/geng 6 -C 0/7
and then I iterated from 0/7, 1/7, 2/7, 3/7
Why the output is 27, 21, 7, 1, 0, 0, ...
How is the subset generated?
Thank you.
When I was actively using SageMathCell for teaching, I indeed got quite
irritated that things that used to work during preparation did not work in
class because of some recent changes. My eventual solution was to run my
own server, where no changes were ever unexpected and in general I had

This is a particular way to encode graph as a string of characters (8 bits

Read Sage docs on Graph for details.

I found it. Thank you.
I also tried the command listed above.
I am confused. Where is this "I]~~w"?
Is it a file? How did Graph load this?
In my program, my code looks like this:
i=12
for G in graphs.nauty_geng(str(i) + " -C"):
q = True
for j in range (0,i):

"languages" for SageMathCell are very different from kernels for Jupyter.
SageMathCell keeps a bunch of preforked kernels (all are the same), so that
new computations don't have to wait for startup. "language" just turns
"code" into something like "print octave.eval(code)", which is then sent to

geng is installed in local/bin/ sub-directory of your Sage
installation, as a part of Sage's standard package nauty.

One thing that comes to mind beyond/independent of preparser tricks (which
can be hard to make robust):
sagecell already has a lot of "languages". Would it be possible to have
sage-py2 and sage-py3 as languages? We could then start out having "sage"
as an alias to sage-py2. At some point we can
On sage-cell, Py3 was brought up. I mentioned how permalinks there may
cause trouble at the eventual Py3 changeover for Sage, since at the very
least print statements will be gone. William brings up an interesting
possibility, and I wonder how/whether this would be useful for Sage proper.

Another question: If I use nautygen and generate huge number of graph, how
do I load into sage?
Because in my for loop, I also use other functions such as Sandpile on the
graph generated by nautygen.
Thanks,

Also, as Python is slow, any part of the nautygen can be written in other
language, such as C/C++?
Thanks,

Hi!
Does either of you plan to open a ticket and make the functionality
available, that according to Jori is present in nauty but according
to Ai isn't wrapped in Sage?
Best regards,
