Primes Arithmetic Progression (PAP) and CPAP
I would like to make a page of reporting prime numbers in
Aritmetic Progression > 1000 digits, here is an example: 0 : 2699# *(41637800*1996857)+2729 Prime 1 : 2699# *(41637801*1996857)+2729 Prime 2 : 2699# *(41637802*1996857)+2729 Prime 3 : 2699# *(41637803*1996857)+2729 Prime 4163780*2699#+2729 AP term 4 difference 1996857*2699#

Your work is fabulous with Ken Davis. In particular, you have shelled the 2371 #. I have a small question if you can inform me: I saw that you are working with newpgen for the sieve. Newpgen can do k * b # + 1 because this form does not need primo for certification. but I would like to make the sieve of k * b # + n. Like my exemple 4163780 * 2699 # + 2729. Are you familiar with a program that can sive it? Thank you.

I took only the primorial form k*p#+1 on top5000AP.txt tanks paul,
the attached files. one litle error: Code p46 in the year 2000 : d=36364*5000# d=187314*5000# d=457410*5000# 5000# should be 4999#.

The gmp version of polysieve should be rather easy to adapt. It is not originally written for this kind of task, but with the correct input it will be doing this. The major modification will be calculating the primorial as it is not doing primorials at the moment. But that shouldn't be too hard.

I downloaded polysieve. But I look for documentation. I dont find it.

I'm afraid there is no documentation apart from what you find in the code.
Just to make sure: What is the running variable in your example?

I gave it a try and I found an AP6 with 10593 decimal digits:
N=(2,738,129,976+n*56,497,325)*24499#+1 for n=0..5
