 2011-08-08, 05:55 #1 schickel     "Frank <^>" Dec 2004 CDP Janesville 2·1,061 Posts Another Aliquot Sequence site I was perusing Paul zimmerman's aliquot page and noticed a new link to a site by Jean-Luc Garambois. Unfortunately, it is in French. The machine translators available (Babelfsh and Google) don't do a very good job of translating the pages to a readable form; is there anyone that could consider making an English translation available?

He has proved that, for any X and N there exist aliquot sequences which go up by at least a factor X at each iteration, for at least N iterations. In http://www.aliquotes.com/problemes.htm there is a list of sequences which he'd like to have pursued to the first iteration at which the number less-than-doubles (ie often until they lose 2^3*3*5); some of the ones >1000000 have only been taken to 93 digits and so would be easy to take for another thirty digits (~100 iterations), though 19560 still has the doubling at 169 digits.

This sounds like a possible subproject for our aliquot project.

(and no, I can't translate this site - my French is q quite rusty, so my translation might be as bad as a google translation.)

Even just a quick summary would be more helpful than the auto-translation. When they do it, it destroys the formatting, breaking the flow of the page.

I think we filled in the work under 1M when we computed all the sequences up to 100 digits....

Should we have a poll about that, or should we just dive right in?

I haven't investigated the auto-translators much. If you contribute to improving the translation of a page, does it flow through to people that come after you?

Maybe just check the translation and help smooth out problems (I assume the machines have trouble with jargon and colloquialisms.)

I'll take a look after work today and see if I can get a better sense of where the major problems are...

Actually not much math....as noted, trying to read the machine translations breaks the page formatting and makes it hard to follow the flow.

Maybe we could make this a community effort (we could work on a full translation when we get tired of watching paint dry....)

I could point a couple of my steam-driven machines in a new aliquot direction, but mon français is worse than mein Deutsch...

You filled in some of it, but to answer his question requires to carry each of the sequences until they lose the 2^3*3*5 driver (and possibly longer in case they lose it in favour of a worse driver), which is often a bit further than we have taken them, and may be an awfully long way.

In http://www.aliquotes.com/problemes.htm, 'Résolution' means someone's working on it, and 'RESOLU' means it has been taken to a point where it lost the driver.

The page formatting looks OK to me looking through google-translate into English.
