COMMENTS

The n-th palindrome starts at A068047(n) and has length A068048(n).

LINKS

Table of n, a(n) for n=1..48.

EXAMPLE

pi = 3.141592653589793238462643383279502884197169399375 ...

a(2) = 535, as the second nontrivial palindrome in pi is '535', starting at A068047(2) = 9 with length A068048(2) = 3.
