[sage-support] Re: Unable to check out trac tickets

[Zachary Gershkoff]

That worked! I did have uncommitted changes because there was a file I 
didn't want to commit, but I removed it from the directory. Creating the 
remote branch the way you said and then setting the branch on the trac 
ticket manually seemed to work.

I would expect the syntax
  S = NN*[2,3]
(which is meant to create the set of NN-linear combinations of the given
generators 2, 3, and is analogous on how one can create an ideal in 
some ring R), but it seems to be not implemented.

Best regards,
Simon

[sage-support] numerical semigroup in sagemath

[springfield .gion]

Hi, I need to create and manipulate the additive semigroups generated by 
integers (such as those generated by tuples of coprime integers), but I am 
struggling with the syntax; is there an easy way to create something along 
the line of:

S = ZZ.Semigroup([2,3])   
S = {0,2,3,4,}

Thanks in advance
