{Universal dendrites}

As it was mentioned in
Property~\ref{ex-Fomega-univ} in~\ref{ex-Fomega} the
\g{locally connected fan} is universal in the class of all $n$-ods,
where $n \in \mathbb N$. Now we recall the construction of
the \gs{Wa\.zewski universal dendrite}{Wazewski universal
dendrite} $D_\omega$ and some other dendrites that are
universal in various classes of these curves.
