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.

P41: 82514915741623328517650484573901437176111P131:79276466536870215660589427037258187228232511168042181233242100341381290510746535680251722466853314074942409563489786970760805952371B1: 3000000Sigma: 2833338313

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.

Hi Patrick,

Here are the factors of Rsm88. This was completed using SNFS.GGNFS was used for the sieving and msieve for the post-processing.

Hi Patrick !

I have noticed a regain of interest for smarandacheconcatenated numbers...

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

Since Bob factorized Rsm78, I can send you the completefactorization of Rsm from 80 to 87... (results for Rsm 81, 82, 85and 87 are archived on M Fleuren pages). I also have found someother factors I'll list at the end of this post since theyaren'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 forsome composites up to 100 (like a p45 not reported yet) andcompleted some of the smarandache and reverse smarandachenumbers (but not the smallest).

To avoid duplication, would you mind to keep tracks of themhere since your pages have a new form or do you prefer continueto 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 arecompletely factored so that nobody will re-do ecm up to 40-45 digits orworst snfs these numbers...Even if you don't enter in details, I would suggest simply that the colourof the links of the top of the pages changes depending of the status of thenumber.For example : grey for factored (even for numbers greater than Sm83 and

Rsm88), violet for unfactored "please refer to M Fleuren text file" and whynot 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 implementyour suggestions, with pleasure. Thanks for helping to improve this site.Much obliged. Patrick.

Hello Patrick,

Here are the factors of Rsm78:3 *17 *47 *17795025122047 (p14) *78119581556663469779307447735538451582384717692143654960846437 (p62) *236415864091491721631173832082837638453438349732083245678426495346687 (p69)

They were found with GGNFS (version: 0.77.1).

See summary file, below.

Cheers,--Bob.

[ June 28, 2005 ]Robert Backstrom (email) factorized Rsm76 ! [ go to entry ]

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.

[ December 30, 2003 ]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 5.0at B1=3 000 000 to catch them (with a celeron 400)...

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

To be continued !

[ July 24, 2003 ]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 contributorof 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 seemsto say it wasn't) but I have factored reversed concatenated smarandache number 65by P-1 method.The factorisation 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 factorisation of the number and Rsm66 and Rsm67 from M. Fleuren tables).I'm surprised that this "small" p31 hasn't been found before...
