Now that <A HREF="http://www.popularmechanics.com/science/math/news/a26815/why-13532385396179-is-a-magic-number/">James Davis</A> has found a counter example, <A HREF="https://oeis.org/A195264">13532385396179</A>, to John Conway's <A HREF="http://gladhoboexpress.blogspot.co.at/2014/10/climb-to-prime.html">climb-to-a-prime conjecture</A>, I would be interested to learn whether this has any implications of interest in number theory.
