A068652
is the sequence of rotational primes. It references
A003459,
the sequence of absolute primes, the numbers of which all
the permutations are primes.
That sequence contains the numbers 1111111111111111111, and 11111111111111111111111.
There's also a link to this page:
MATHEWS: Circular, Permutable, Truncatable and Deletable Primes,
which lists all known rotational primes.
According to that list, you probably won't find any more rotational primes.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
