Documentation error in ncsf ?

[0-andy-0]

Steps To Reproduce

open https://doc.sagemath.org/html/en/reference/combinat/sage/combinat/ncsf_qsym/ncsf.html

Expected Behavior

Maybe should say: Over QQ (or any other Q-algebra), this Hopf algebra Psi is isomorphic to the universal enveloping algebra of its space of primitive elements. The primitives form a countably generated free Lie algebra, so Psi is the tensor algebra on a countably infinity dimension vector space.

Actual Behavior

Says: Over QQ (or any other Q-algebra), this Hopf algebra Psi is isomorphic to the tensor algebra of its space of primitive elements.
