On the puzzle invented in http://list.seqfan.eu/pipermail/seqfan/2010-August/005620.html :

It seems these are primes that appear both as odd cyclic numbers and factors
in a single line in http://www.numericana.com/data/crump.htm
(Carmichael Multiples of odd cyclic numbers). At least the four first of these
primes match that pattern.
