Things Have Changed

Since I last submitted that paper.

1. The journal that had been interested in publishing it no longer publishes things on that subject.
   
2. A paper can be turned down in 2 days.
   

Still, the "rejection" was very encouraging, saying

I would urge the author to submit his paper to a top-end number theory journal...

So I will, but I have to do some further (minor) reformatting.

New Version of "There Are Infinitely Many Perrin Pseudoprimes"

I have reformatted There Are Infinitely Many Perrin Pseudoprimes (sometimes known as "There Are Infinitely Many Frobenius Pseudoprimes"). It now uses a more modern version of the TeX typesetting package. I also re-submitted it for publication after only 6 or 7 years. I think it holds up, though!
