[QUOTE=science_man_88;226226]now if I only I could be smart like you so I could build you that helpful program lol.[/QUOTE]

[i]I'm[/i] not smart enough to write that program, but maybe you are. You have a long way to go, though!

Here are some possibly-relevant papers in case you decide to think more about this:
[url=http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.132.8640&rep=rep1&type=pdf]mArachna – Ontology Engineering for Mathematical Natural Language Texts[/url]
[url=http://mathweb.org/projects/mws/pubs/mkm08.pdf]MathWebSearch 0.4: A Semantic Search Engine for Mathematics[/url]
etc.

[QUOTE=3.14159;226232]?a = a(n) = nextprime(10^n))[/QUOTE]

I'm sure it didn't say that -- it's not in the form of a valid closure. But if it said
[code]a(n) = nextprime(10^n)[/code]
then it would never return 2 for n >= 1 -- it's a constant, no randomness.

Now: Can we get back to the substitutions required to make the sieve for the k * n + 1?

Why don't you just download srsieve and use that? It'll be faster.

Because it can only sieve for Proth numbers.

It does more than Proth numbers. What, precisely, are you sieving for? Can you specify exactly for me?

k * n! + 1.

Maybe this?

Possibly even this?

The first is source code, luckily I downloaded some freeware to deal with C source code.

Nevermind that. I'm going to go to Generalized proths, using factorial and or primorial powers, just need a larger base range. Anything for that?

I can never keep track of all the names (especially since some are contradictory... e.g. several definitions for generalized Fermats). What form are these?
