Hi seqfans.
\par
For example, to make a link to \anum{006125} use the small command
\begin{verbatim}
\anum{006125}
\end{verbatim}
instead of
\begin{footnotesize}
\begin{verbatim}
\htmladdnormallink{A006125}
{http://www.research.att.com:80/cgi-bin/access.cgi/as/njas/sequences/eisA.cgi?Anum=006125}
\end{verbatim}
\end{footnotesize}
\par
Type 13 chars instead of 117 chars. Yep, $117 /13 = 9$.

A new comment on \anum{006059} (Connected labeled topologies with $n$ points)
and \anum{001035} (Partially ordered sets [``posets''] with $n$ labeled elements
[or labeled acyclic transitive digraphs]):
%A006059(n)=n*A001035(n-1), n>0
\begin{equation*}
\anum{006059}(n) = n \, \anum{001035}(n-1) \quad ,\text{for } n>0
