Description (last modified by )
Patch under development on the Sage-Combinat queue:
http://combinat.sagemath.org/patches/file/tip/trac_11109-stable-grothendieck-polynomials-nt.patch
The current implementation currently gives incorrect results, due to a missuse of the Pieri factors. It will be fixed by adding another feature there.

Oh, merci Frédéric!
I need to dive back into the code and algorithm for there remained a problem to fix. From the top of my mind, one needed to have access to some more combinatorial information on the Pieri factors.
