The spt_gap table shrunk from 603254 rows to just 42592 or 3 MiB. Which means that the asimilator is now working in real time.

These are incorrect tuples!
Not all numbers are prime here.

The incorrect results mentioned in https://boinc.tbrada.eu/forum_thread.php?id=3055&postid=3781 are re-appearing in the database.
This is unacceptable.

I added more validation conditions into both asimilator and db rebuild program.
Namely: wheter the tuple is really symmetric
and also check that the numbers are indivisible by primes<80000 (probable primality test).
Also duplicate tuples are now not saved into the DB.
The rebuild program is now running. Then we compare the previous version of db with the rebuilt db.
I will later try to incorporate the requirement for truncated SPT(14).

Process phase finished. But tuple database not good yet.
Todo:
284009 / 345718 +inv270 #2189806               Invalid: check_symm_primes composite start

And figure out what intervals are affected by beta app having wrong I/O format.

# where kind = tpt
# where k = 10

Here used to be a solution.
Or two solutions
tpt 10 3324648277099157 52 16 10 64 10 16 58 22 28
tpt 10 31910610414019031 34 22 94 28 10 10 58 106 46

The database is not restored?

Excellent!
You can create a sequence similar to https://oeis.org/A259034

The terms
3324648277099157, 31910610414019031, 55016223757181177, 177564738317068181

This is enough to start the sequence.
Indicate that the first term in the sequence is a (1) = A087641 (10).

Note.
The solutions actually look like this
3324648277099157: 0 2 54 56 72 74 84 86 150 152 162 164 180 182 240 242 264 266 294 296

It seems that these entries were mistakenly assigned the full STPT(14), they are only STPT(12), and also SPT(14).
I am not sure. I need to add check to the validator and investigate which batch these came from.
Batch: 61, user: 13622, result: 2508934. It has the "truncated" flag set, so the error might be in the truncation code of STPT specifically.
Derived from STPT(16) 2640138520272677. I think I found the error.

I created an account at OEIS and currently I am studying on how to correctly create a new sequence.

I created an account at OEIS and currently I am studying on how to correctly create a new sequence.

Try to start by adding solutions to existing OEIS sequence https://oeis.org/A256234
These solutions are found in the TBEG project

Provide a link to the TBEG project.

The following solutions are found in the Stop@home project

The OEIS article has a link to the Stop@home project; indicate in the comments that this project is currently not working.

The article has an attached b-file
https://oeis.org/A256234/b256234.txt

You have to change it.
This file says
# Tested up to 5*10^17.
# Dated 17 May 2017.

This also needs to be changed.

After making changes, do not forget to click the button below.
A draft sequence should appear, you will see it.
Then there will be a discussion with the OEIS editor, he will tell you his notes.

The defects described in the linked message in assimilator were corrected and the whole database is now being reasimilated to eliminate the erronous tuples.
As such, normal asimilation of completed wus is paused until this process is over.
