[sage-combinat-devel] Problem with the nilcoxeter algebra

2013-01-19 Thread tom d
There's been a change to the init function for the Iwahori Hecke Algebra that causes the NilCoxeterAlgebra to fail. I _think_ this is happening in the affine_iwahori_hecke_algebras.patch; the nilcoxeter algebra is still working fine with combinat unapplied. There's an extra parameter

Hi Tom, Dan Bump, Dan Orr, Mark Shimozono and I will work on this patch during the Sage Days at ICERM. It is not yet close to its final form, so just disregard it for the moment. Everything is likely to change soon! Best, Anne On 1/19/13 4:28 AM, tom d wrote: There's been a change to the init
