Hi Christian,
well, I have not yet uploaded this patch to track, because I do not
feel very confident (the procedure seems too complicated to me..) If
somebody has some time to help..
By the way, do you know if there is a way in Sage to try something on
all posets of size 6, 7 or even 8 ? I
Hallo Christian,
Which version of sage are you using? With sage-4.5.3 everything
seems to work fine for me. I think Florent recently changed
something in this patch in all.py.
I can try to install sage-4.6, but it will take my computer some
time to complile ...
Perhaps run sage -combinat update
That sounds amazing. Assuming enough people submitted often enough, it
would be the best screensaver ever. If there were enough users for it
to be real-time it would be even cooler.
