Where or how are they going to be shown for the user?
Will it show somewhere on the User Your account Page?

They're all here: https://sech.me/ap/. Download 19-digit and 20-digit files and search for "BOINC". But I can write a script to export it somewhere else as well.

Each pair is listed under the name of this pair's discoverer. Search for "bcavnaugh" in 19- and 20-digit files. There are 38 pairs found by you so far.

Yes, everything is saved. For example, pairs found yesterday: https://sech.me/ap/log/2017/2017-02-05/VOLUNTEERS%40BOINC.txt

But yes, a list of found pairs on a user profile page will be much better. It's in my TODO list.

This may belong in the other thread but you might consider badges based on the number of found pairs since those are more useful to this project than credits.

Yes, definitely. And these badges will be more valuable because the total number of undiscovered amicable pairs < 2^64 is only ~500,000.

I have been credited with 12 found Amicable Pairs, however I only have 11 as one of the pairs does not have my name on it (Number 10 in my list)

10 56 "BOINC: Bryan, Bok" 2017
14221265135670852490=2*5*7*11*347*5711*21943*424727
17792582086750962806=2*7*67*71*101*223*347*421*81197

This needs to be credited to the correct people.

Thanks

It's credited to them already. I'll check why it appeared on your list.

P.S. It was a bug in an import script. There were more users affected by this bug. All fixed now.

>Each pair is listed under the name of this pair's discoverer.

Since each work unit is run on two different computers (by two different users), my question is this: if a amicable pair is found, will both users be credited as discoverers? Or only the user who reported it first? (The former would make the most sense to me.)

They're both mentioned as discoverers in the order they completed the corresponding work unit.

I take it when only one person is named as discoverer that they ran the work unit on two of their own computers ?
Just checking as you didn't counter the 'by two different users' statement.

Exactly. It makes no sense to repeat the name in this case.

Message 733 - Posted: 10 Feb 2018, 18:19:33 UTC - in response to Message 719.  

Hello, I have a question: What does number mean before people who find pair? For example:
1 74 "BOINC: Martin Droppa, Beyond" 2018
39094555702914362872=2^3*13*29*193*293*1979*5623*20599
43332034116567237128=2^3*73*1249*798503*74397311

What does 74 mean?

Thanks Martin

Message 734 - Posted: 10 Feb 2018, 18:24:47 UTC - in response to Message 733.  

It's a type of amicable pair. Detailed explanation: https://en.wikipedia.org/wiki/Amicable_numbers#Regular_pairs.
Short explanation: first digit is the amount of unique prime factors in the first number, second digit is the amount of unique prime factors in the second number.

In this pair:
- 13, 29, 193, 293, 1979, 5623, 20599 (7 factors) are unique to the first number
- 73, 1249, 798503, 74397311 (4 factors) are unique to the second number
