Another merge 41^32 ?
Base 41 can be added at your leisure.

41^32:i386 = 271980:i46
Edit: I'll also take base 42 to initialize. Last fiddled with by Happy5214 on 20210214 at 01:20 Reason: Taking base 42

Base 41 was taken to i=77 as will base 43 be taken to the same.

Base 42 done to 80 digits (odd exponents; 42^47) and 120 digits (even exponents; 42^72), and as soon as I wrote this, I think I misread https://www.mersenneforum.org/showpo...&postcount=762 above in reference to there being a new minimum. I wasn't planning to take this base to work on past the seeding work, so I could take it to the usual 100 digits or yoyo (or someone) could take it from here.
Exponents 1, 3, and 5 terminate with primes. There were two merges: 42^11:i131=35320:i2 and 42^17:i361=239940:i3. All even exponents tested terminated with primes, including 42^34, which terminated on the first term. Interestingly, 42^16 picked up a square and became even for two terms, before picking up another square and terminating two terms later.

Thank you all for your precious help ! Thank you for reporting any errors regarding your work, your reservations, your current initializations, your mergers... The update was laborious ! Added bases : 37, 41, 392, 450, 882 and 33550336. Bases reserved for yoyo : 439, 496, 770, 1155, 33550336. Bases being initialized which will be added during a next update, I will wait for your signal : 34 (YOY), 35 (YOY), 42 (YOY), 43 (RFD), 578 (EDH), 8589869056 (YOY). Edit : When I look at the tables for bases 37 and 41, I think we forgot some merges, especially for base 37 ! But sorry, I really don't have enough time today to take care of this ! I will see for the next update ... Last fiddled with by garambois on 20210214 at 12:29 Reason: Addition of a remark for mergers of bases 37 and 41 and Change of "42 (HPP)" by "42 (YOY)".

Note that it uses the 80 digit file, so it won't pick up those few merges we found that are outside that.

OK, many thanks for your help, because I don't have a script : I look for the mergers manually and it can take a long time ! Does it use my 80 digit file, on my website ? Because I know that I will also have to update this file : in a year, things move because of the sequences which merge and which end ! And I hope that when I scan the over 27,000 sequences in the main project, I won't find any broken aliquot sequences !

I have some expansion to do with my script, so I can call it easier and I need to address the i0/i1 error. At some point, if I get it working the way I'd like, I'll post it here. It's a simple Bash script that runs on one of my RPi machines. Here are some runs for today: Code:
