Hi Everyone,
Something in the sage-combinat queue appears to be break
CombinatorialFreeModule.
Using the unpatched version of sage 5.5 I get the following expected
behaviour:
----------------------------------------------------------------------
| Sage Version 5.5, Release Date: 2012-12-22 |
| Type "notebook()" for the browser-based notebook interface. |
| Type "help()" for help. |
----------------------------------------------------------------------
sage: CombinatorialFreeModule(QQ, [4,3,2,1]).sum_of_terms([(i,i) for i in
[4,3,2,1]])
B[1] + 2*B[2] + 3*B[3] + 4*B[4]
If I now apply the complete queue and try exactly the same command then we
get the AttributeError below.
It's late in Sydney so I haven't tracked down the patch which is causing
the problem...but my guess is that (fixing and) unguarding
trac_7980-multiple-realizations-nt.patch might help?
Cheers,
Andrew
