PrimeForm or PFGW

To calculate the length of a Smarandache number in PrimeForm you just enter at the prompt

pfgw64 -od -f0 -q"len(Sm(119))"

For the reversed Smarandache number you type

pfgw64 -od -f0 -q"len(Smr(119))"

Consecutive Number Sequences
http://tech.groups.yahoo.com/group/primeform/message/10253

After ~12 years of on-and-off searching using spare CPU cycles, it seems I've found only the second known reverse consecutive integer (probable) prime. And it's a big one:

37765 37764 37763 ... 5 4 3 2 1

(spaces denote concatenation here; not multiplication) with 177719 decimal digits. The only previously known such prime was the 155-digit number:

82 81 80 ... 5 4 3 2 1

Patrick,

I decided to run a little ECM on the 7 remaining Rsm's 100 and below, and found a factor.
Rsm96 splits as p41 * p131.

Hi Patrick,

Here are a couple more factorizations, both by SNFS using GGNFS and msieve.
At this point, they are getting more difficult so more ECM is needed.

Philippe Strohl (email) completely factorized Rsm80 to Rsm87! [ go to entry ]

Hi Patrick !

I have noticed a regain of interest for smarandache
concatenated numbers...

I have done some ecm work on them a year ago...

Since Bob factorized Rsm78, I can send you the complete
factorization of Rsm from 80 to 87... (results for Rsm 81, 82, 85
and 87 are archived on M Fleuren pages). I also have found some
other factors I'll list at the end of this post since they
aren't reported elsewere...

Thanks a lot for maintaining these pages.

Best regards.
Philippe Strohl.

P.S. : I have found some interesting "not so small" factors for
some composites up to 100 (like a p45 not reported yet) and
completed some of the smarandache and reverse smarandache
numbers (but not the smallest).

To avoid duplication, would you mind to keep tracks of them
here since your pages have a new form or do you prefer continue
to record only results for the smallest unfactored number,
which nicely increase the suspens and emulation ?...

What I mean is that your pages could mention that these numbers are
completely factored so that nobody will re-do ecm up to 40-45 digits or
worst snfs these numbers...
Even if you don't enter in details, I would suggest simply that the colour
of the links of the top of the pages changes depending of the status of the
number.
For example : grey for factored (even for numbers greater than Sm83 and
Rsm88), violet for unfactored "please refer to M Fleuren text file" and why
not yellow for "an unreported factor is known, please contact me for details"...
You would just have to add a legend below the links...

Philippe, your arguments are very convincing, so I will follow and implement
your suggestions, with pleasure. Thanks for helping to improve this site.
Much obliged. Patrick.

Hello Patrick,

Here are the factors of Rsm76 and Rsm77 for your tables.

Rsm76 was done using GGNFS (written by Chris Monico),
and I'll include the summary file below.

Rsm77 was done using ECM.

Philippe Strohl (email) completely factorized Rsm67 ! [ go to entry ]

Hello Patrick !

I wrote to you a few months ago for the factorization of the Rsm65.
I'm now back with the harder factorization of Rsm67, a c113 that is in fact
a p40 * p73... It tooks me more than 2300 curves with gmp-ecm 5.0
at B1=3 000 000 to catch them (with a celeron 400)...

The next "unknown factorization" for reversed smarandache concatenated
numbers seems to be Rsm76...

To be continued !

Philippe Strohl (email) found all the factors of Rsm65 ! [ go to entry ]

Hello Patrick!

My name is Philippe Strohl, I am a french Vet and a modest contributor
of A Kulsha, H Mishima and D Alpern (modified fermat numbers) projects.

I don't know if this result was known (your site and M. Fleuren file seems
to say it wasn't) but I have factored reversed concatenated smarandache number 65
by P-1 method.
The factorization is :
Rsm65 = 65646362.....4321 = p1 * p1 * p2 * p5 *p5 * p31 * p79 = 3 * 7 * 23 * 13219 * 24371 *
8388659548971249567207085659037 * (proven prime)
5029201255469786028962125207969872821464255213510243858630692908421051327966799 (proven prime)

You will find the details following in this mail (gmp-ecm 5.1 beta output screen,
p-1 factorization of the number and Rsm66 and Rsm67 from M. Fleuren tables).
I'm surprised that this "small" p31 hasn't been found before...

Philippe Strohl.

Hi Patrick,
here's the next found, not expected so fast.
I've done some ecm-work over night and found this:

prp53 = 22633393225636817509048253413614523936779379142819839
      (curve 50 stg2 B1=260000000 sigma=4172026601 thread=1)
Finished 400 curves using Lenstra ECM method on C160 input, B1=260M, B2=gmp-ecm Default

The same machine as last found (i7; 3,4GHz, 8 threads).

A ggnfs-run would have taken about 7 days I think and such found so fast was unexpected.
I'm running more ecm on RSm 105, the C156 first before sieving.

Best regards. Karsten Bonath
