Hi everyone, I'm doing this:
sage: FreeA.<a,b,c,d,e,f> = FreeAlgebra(QQ,implementation="letterplace") sage: P = a*b*a*c*c*b + a*b*a*d*d*b + a*c*a*d*d*c + b*c*b*d*d*c sage: X = P.lm() sage: X a*b*a*c*c*b And now I would like a way to "cut" my element X into two factors of a given size. Something like sage: u,v = X[:2],X[2:] with then u=a*b and v = a*c*c*d except this doesn't work (no __getitem__ on X). I have looked a bit, but I cannot find how to do this even though it seems quite a natural operation. I must say, I don't even understand the datastructure of X, list(X) doesn't give me something I can easily read or transform into a word or anything... If someone knows about this, I would appreciate the help. Thank you Best Viviane -- You received this message because you are subscribed to the Google Groups "sage-support" group.
