4775

[N. J. A. Sloane]

as jud points out, all its prime factors are palindromes.   so i've added this
sequences:
%I A033620
%S A033620 1,2,3,4,5,6,7,8,9,10,11,12,14,15,16,18,20,21,22,24,25,27,28,30,32,
%T A033620 33,35,36,40,42,44,45,48,49,50,54,55,56,60
%N A033620 All prime factors are palindromes.
%R A033620
%O A033620 1,2
%K A033620 nonn,base,more
%A A033620 njas

but 4775 won't appear there for a long time
