Talk:Permutable Prime with more than 3 Digits is Probably Repunit

This has not been proven.

Instead, both:

• Mar. 1977: Allan W. Johnson: Problems (Mathematics Magazine Vol. 50, no. 2: pp. 99 – 104)  www.jstor.org/stable/2689738
• Jul. 1995: Dmitry Mavlo: Absolute Prime Numbers (The Mathematical Gazette Vol. 79, no. 485: pp. 299 – 304)  www.jstor.org/stable/3618302

show that these numbers are either repunits or of the form $aa \dots aaab$ with absurdly large number of digits and many restrictions.

On the existence of absolute primes only proved there are no permutable primes where all the digits $1, 3, 7, 9$ appear. --RandomUndergrad (talk) 05:43, 23 July 2020 (UTC)

Yes, I'm not sure what I was thinking of when I wrote this page. Nowhere in Wells does it make that statement. I will rewrite this page to say what the above citation actually says. --prime mover (talk) 06:25, 23 July 2020 (UTC)

That should cover it. Well researched.

It remains to post up the proofs given in these papers. --prime mover (talk) 07:22, 23 July 2020 (UTC)
