Could you write, that primes in Sierpinski base 1027 from n≈129000 entering TOP5000?
Pre-thanks

They are too small to enter TOP5000.

oh sorry take 1 "0" more, than real
EDIT:
Wait...
I took my last task and there is length of number from it http://wolframalpha.com/input/?i=IntegerLength%5B75744*1027%5E137435%2B1%5D
But on http://primes.utm.edu/primes/status.php
We can see that

make the top 5000 today a prime must have 391556 digits or meet the size requirements for it's archivable form.

Interesting link to calculate the digits. I have changed the info in the base loaded thread.

You can also check this with PARI/GP

gp > length(Str(75744*1027^137435+1))

I took this method of calculating number of digits from submission page of PRP Top by Lifchitz

It should be possible to write an script to check at which n-value Top5000 primes are "available" using the gp-code I noted.
IF I have spare time, I´ll bring a list of it either in mersenneforum or here.

Is it hard to calculate entrance number of digits to TOP5000/log10(base)?
