14 digits is complete? 15 digits odd is complete? What about 15 digits even? I still don't have many machines back up. I'm also not sure where I will point them when I do...

14 digits even numbers are moving slowly. Hopefully this range will be finished in a couple of months. 15 and 16 digits odd numbers are finished. I did not start 15 digit even numbers range.

P.S. I still haven't checked up to see how/why I missed that 4cycle you found in my early range. The machines that would have that info aren't back up yet.

At last, I completed the search of all 14d even cycles. I hoped to find at least one cycle of length different to four. Unfortunately none of them is there. On the other hand, three new cycles of length four were found on top of Ed's eight cycles.
I am currently testing the program for 15d even cycles. It works considerably slower than that for 14d even and 16d odd cycles. Anyway, at some point I will post it on this forum just in case if someone is interested in the project of looking for 15d even cycles. I will pursue it for some time but definitely I will not accomplish it. I still hope to find at least one cycle of length different to four. :)

Again more than tripled the number of sociable cycles, added 3817 cycles, the new count is 5410, see
http://djm.cc/sociable.txt In the table 1067 of them is irregular, the previous count was only 70. The largest cycle has 90 digits: Code:

Congratulations on this latest update Robert! Can you please comment on if these are all 4 cycles and what types you have searched for.
Thanks, Andrew.

It is not a type search method. As I can remember in the past I've discovered the first known (0,0) [exotic] type, I've even not noticed this immediately, because it wasn't a type search algorithm. Last fiddled with by R. Gerbicz on 20171203 at 10:05
