Dear all
The OEIS was referring to a preprint of Travis Sherman only a copy
of which
was accessible through
archive.org.
But a page was misprinted in
that copy.
I contacted the list, then Travis Sherman: only Victor Miller
happened to have
miraculously kept an essentially clean copy---that was given to him
by John Brillhart.
T. Sherman did not succeed in finding one, but agreed we could put
Victor's one
to the OEIS.
Then Maximilian Hasler was kind enough so as to import the clean
version
to the OEIS and to modify the (17 I think) references to it.
This message is both an information and an opportunity to thank all
the colleagues
who helped, in particular Travis Sherman, Victor Miller and
Maximilian Hasler.
Best wishes
