# Isprime(10^n+1)

From OeisWiki

## History

On 2000-05-18 at 00:00GMT Marvin Ray Burns conjectured that there are only a finite number of primes of the form 10^n+1 (Cf. http://math2.org/mmb/thread/8430.)

This thread (Cf. http://math2.org/mmb/thread/26008) tries to show that the integer sequence of such primes is

- {2, 11, 101}

and there are no more.

## 10^(2^n) + 1

Only generalized Fermat numbers of the form

may possibly be prime.
