I suggest that these sequences may be useful.
Code:
forprime(x=1,500000,if((10^100-1)%x==0,print1(x",")))
looks to generate the first sequence, making it a normal for loop generates the second I believe. I figured a few things out first using other PARI scripts.

Why can't I get http://www.alpertron.com.ar/googolm1.pl (prime factors of googolplex-1) to come up? I keep getting an HTTP 500 Error. What's wrong with it?

The error was a missing #!/usr/local/bin/perl in the first line of the script. There was no problem when using the old Web server which had Windows. The new Web server uses Linux and it appears that the first line is mandatory.

it's easy ( must be if I can do it just ask everyone on mersenneforum.org) to show this is a subsequence of the original definition at very least:

we start by proving a^p-1 | a^(px)-1, done this this we continue by showing that a^b-a =a*( a^(b-1)-1) knowing a = 10 and b=10^100, b-1=10^100-1 =px find prime p dividing 10^100-1 and that's proof that it's at least a subsequence. just thought I'd give you a basic concept of how i'd go about proving it.
