Hi everybody.

Thankfully that works great. There is o

Hahahahhahaaha ! Dead right :-)
And the code works anyway because the tree it returns actually is *NOT* a
BFS tree :-)

Hi,
Unfortunately, I don't think there is support for this feature at present.
If there were, it would likely be implemented via the Settings link in

Hi Nathann,
First, thank you for taking time to give a very detailed reply.
I'm sorry but I'm not yet done bothering you :-]
I think this is wrong:

How make typesetting be the default in all notebooks?
(i.e. I don't want users to have to check the Typeset checkbox all the
time.)
Sincerely,
Chris Seberino
P.S. I tried googling for it but could not find the answer.

Hellooo Jan !
It is 20:20, it is almost dark outside and I am getting home by bike.
Worst of all, I am being assaulted by hungry mosquitoes. I re-read it
the following enough times to be sure that if I miswrote "v" instead
of "x" somewhere, reading it again wouldn't have changed anything.

I see you downloaded a prebuild binairy, I guess what's going wrong is that

Hi Nathann,
after this line (line 9520 in

How can one be sure that x and y are still connected? (otherwise no

In your code, ComSet is a Python list (not a set) as are many of its
components, and you use len(x) to get the size:
sage: ComSet, type(ComSet), len(ComSet)
([[[0, 1], [0, 2], [1, 2]], [[0, 1, 2]], [[0, 1], [0, 2], [1, 2]]],
, 3)
sage: ComSet[0], type(ComSet[0]), len(ComSet[0])
([[0, 1], [0, 2], [

I'm afraid that's not working. Appartently len has been removed and replaced
with cardinality(). Thanks for the tip about ".[tab]". However I still seem
to be rather stuck:
If I run this code:
Columns=3
Rows=3
RowVector=[2,3,2]
ComSet=[]
for j in range(Columns):
C=Combinations(range(Rows),RowV
Many thanks for this. Apologies for incomplete code: Columns=3.

Dear all,
If I have a list, how do I obtain the cardinality of the list, the
command Cardinality() doesn't seem to always work. For example, the
following code produces a set ComSet of sets of combinations.
Rows=3
RowVector=[2,3,2]
ComSet=[]
for j in range(Columns):
C=Combinations(range(Rows)
