Actually, they're doing pretty much the same thing. A stream models

While this is certainly true mathematically, you might run into trouble
computationally.
In a (additive and commutative) monoid M there is a (unique) x in M such
that for all m in M it holds:

I am about to give a talk about Sage, any feedback is appreciated. I
am using Keynote on a mac, so the pdf does not look as good, but
presumably more of you can take a look this way. There is a short
movie and demo worksheet too:

As far as I can see, it looks really great!

Hey Marshall ...
I just had a glance, and it looks great! Out of curiousity, who is the
intended audience?

Mostly undergraduate math majors, but there will be some faculty there
from various departments who might decide to use sage in teaching or
research.

Thanks for the feedback. I'll add a world map first. I do use my
slides as a counterpoint to what I'm saying, so there are a lot of
gaps I fill in verbally.
I will be revamping this talk into another version I will present at
another university, so anything else is appreciated. Jason has

Sorry for the double post:
* #4105 is still open, so I would not expect your bug to be fixed :)
* #4138 was a general cleanup of PermutationGroups which has been
merged and claims to fix #4105, but it does not.
So in the end someone needs to fix #4105.
Cheers,
Michael
