I come from Germany, NRW.

I'm interested in numbers, especially Mersenne Primes and Wieferich Primes. However my level of understanding of number theory is nowhere near that of a mathematicians. Please have little bit of patience with me. Email: [email protected]

1. Mersenne Primes A000043, A247473
2. Wieferich Primes A001220, A001576
3. Near-Wieferich A246568, A385856
4. Others A385924

footnote:
[1] by Johnson (1977) (see A note on the two known Wieferich Primes)

• his formula for the Wieferich primes is
  • " (base 10)"
  • " (base 10)"
