# Hopf algebra with a non-grouplike invertible element

What is an example of a Hopf algebra $$(H,Delta,epsilon)$$ containing an invertible element $$h$$ which is not grouplike: An element $$h in H$$ such that
$$Delta(h) = h otimes hqquadtext{(grouplike)}$$
and such that there exists a $$h^{-1} in H$$ with $$hh^{-1} = h^{-1}h = 1$$ (invertible).
