Apparently, LLR uses 3/2 as the seed, and this paper says one can use 1/4, but I see no proofs

 Anton Vrba has provided a proof for the sufficiency of Conjecture 2, but failed to prove the converse.
Do you have a link to Anton's proof?

Edit: Found this one by Robert Gerbicz. So our years of Wagstaff PRP crunching was sound.

Yes. I've seen that recently. Robert Gerbicz used 3/2 mod N and Anton Vrba used 6, in 2008 October.
See: Gerbicz and Vrba .
Berrizbeitia's paper is 2010. But Melham's paper is 2008, final version received 2007, April 17. Melham first.
Melham, Vrba, and I thought about the same LLT ideas and provided different proofs (with different seeds, but that is not an issue).

[offtopic]Colleague is some one of your rank (society's class), not your college class. It is someone of your level whom you work together, not study together. A person with whom you studied together is your classmate.

And of course, it is still totally unclear whom you were even talking about. [/offtopic]
