Comment:
Add a strong generating system method.
I really need this method and so, this first implementation is not very
good. The data structure (list of list) is dense and perhaps not very
adapted (the python list begin at zero and the structure should be in
correlation with positions and integer...(Dictionary? , family?, ...) ).
This is really not optimized (I am waiting for LinGap...). If it goes in
Sage as a first version, one could easily improve it...
Comments, corrections, suggestions welcome!
Wdj : What kind of problem ? Is it a problem of export ? ... On the sage-
combinat queue, the two patch work well...
