Yes, thanks Mike.
Tom, Greetings,
Re: Mersenne numbers, Mp163
..MZD03-Oct.MPTH163
The search for Mersenne primes begins by looking for
small factors of (mersenne numbers) 2^prime -1.
That's what I did.
My letter proves a low factor for 2^163-1.
Showing (on a pocket calculator) that it ISN't a Mersenne PRIME.
I have photographed mersenne number plates MP163 and MP67
in my (one street away.) And Mercurial factorisation HG 7817 etc.
LN 2718, PI 315, PI 180. All in Newtown.
Sums of squares 4916, 5096 at Wellington Hospital 2003.
= 70^2 + 14^2 == 5200 -2*52.
= 14^2 x(5^2+1.)
I have also eliminated some exponents about recent world
records on sci.math , groups.google.com.
About 2^(13.4 million) -1.
e.g. 'twin primes about mersenne prime exponent.'
or 'factors of mersenne numbers.' ?? 80mill... divides M_13mill...

Gimps require one supercomputer week to prove
the world's largest known prime number. After it has been
selected by 200,ooo distributed personal computers.(??)
Penguin dictionary of curious +interesting numbers states (1987)
29th mersenne prime = M_132049.
This held me up for a while. The revised edn (David Wells 1997)
gives that Mp as the 30th and inserts a more recent
M_110503 as 29th. Unfortunately I missed that
interesting date 11.05.03 and 25th = 21.7.01.
29th = 1.3.2049 etc.
there seem to be lots.
They are supposed to say (probably-possibly the 40th Mersenne prime)
if not all indicies have been checked twice.
Readers Guide abstracts reported M_858433 is prime?.
I confirmed a FACTOR and possibly reported a typo.
In fact it should be M_859433 may be prime.
I advised author David Wells of a number of errors in [1987]
and he acknowledged me in Revised Edn [1997.]
(I claim 1/*61 and 7^*510 and 1215306625.eis)
I have about 45 sequences in On-line encyclopedia of integer sequences.
search google njas research eis lookup.
Thank you

We look at the usual long multiplication of, for
example, 123*48.
