COMMENTS

No more terms < 10^14. - David Wasserman, Jul 21 2005

The sequence is infinite. One can always multiply an n-digit palindrome by 10^n+1 to get another term. - Franklin T. Adams-Watters, Jun 06 2006

a(25) > 10^18.

Table of n, a(n) for n=1..24.

EXAMPLE

a(6) = a(7) =a(8) = 2112

2112 = 2*2*2*2*4*33

2112 = 2*2*2*2*2*2*33

2112 = 2*2*2*2*2*2*3*11
