What is the valids value for this chain? What number does the chain highlighted in green start at?
These questions are not addressed to me, but I will take the liberty to answer them.
If for some unknown reason you are interested in collecting chains with passes, this does not mean at all that it is interesting to others. Moreover, you were clearly told that others were not interested.
However, I will tell you the procedure for how this chain can be found.
1. You are requesting the full log from Natalia Makarova.
2. After receiving it, you find a line in the log where the "1" in the position of interest appears for the first time.
3. In the next line above you find which prime square permutations were used.
4. You count these permutations in the PARI\GP program and print the lines.
5. Find the line of interest and define "valids".
And a couple more remarks.
1. No one will do this except you.
2. The funny thing is that this line may not appear at all in the output of the program on PARI\GP. Because it can be pre-filtered.
From point 2 above it follows that your question about the “valids” of this chain is mathematically incorrect. It may simply not have it. Ha-ha.
