Gavin,

I have stated in this post:

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&c2coff=1&safe=off&selm=67828976.0207060804.7caff93c%40posting.google.com&rnum=1

that there are a lot of errors regarding the 196 number.  To quote
myself:

"99% of the web pages on the Internet regarding the 196 Palindrome
Quest believe that 196 is the only number that does not solve out (or
the only number under 10,000 that does not solve out).  This is not
true.  Obviously, 691 (196 reversed), or 295 (the outer digits equal
the same sum: 1+6 = 2+5) both do not solve out either, because after
the first iteration of these numbers, they all result in the same sum
as 196 does after one iteration: 887 (and thus, 887 never solves out,
either, since it is the second step of the 196 sequence).  Find more
about Lychrel numbers (numbers that do not solve out via
reversal-addition) on Wade's pages: http://www.p196.org/"
