It seems natural that $W^{1,\infty}(\Omega)$ should embed into $W^{1,1}(\Omega)$ when $\Omega$ is bounded (possibly with some further regularity conditions on $\Omega$).
Indeed, this is covered by a result stated without citation on the Sobolev space Wikipedia page.
However, in both the Maz'ya book, and the Adams & Fournier one, the big Sobolev Embedding theorem statements all seem to restrict to $p<\infty$.
Is there an embedding of $W^{1,\infty}(\Omega)$ into $W^{1,1}(\Omega)$ under some assumptions on $\Omega$? Can you provide a reference for this? (Maybe it's just too obvious to warrant stating?)
