I agree that this would be awesome, but I have no idea how it would
be implemented. I think that when you type "2**18" into Spotlight
it calls the calculator application in OS X, instead of handling the
calculation itself. If you could reroute the call to Sage you might
be able to make something ha
Hi,
Is there any particular reason why when one tries to iterate over
IntegerVectors(k,n) one gets the vectors represented as lists and not
tuples? The only difference between the two that I can think of is
that lists are mutable and tuples aren't. I cannot see why being
mutable is an advantage. On

Probably. Alternately, we could change our use of to_poly_solver in
solve() to use the sane_variables option or whatever it is, which
always makes the variables nice like that.
