%N Palindromes in A085932.

%C Sequence is infinite since there is no restriction on the number of zeros.

%C This sequence is the union of {1, 2, 3, 4}, {2*100^k + 4*10^k + 2}, {2*100^k + 9*10^k + 2}, {4*100^k + 8*10^k + 4}, {6*100^k + 7*10^k + 6}, {100^(k+1) + 8*10^(2*k-m+2) + 5*10^(k+1) + 8*10^m + 1} and {8*100^(k+1) + 10^(2*k-m+2) + 5*10^(k+1) + 10^m + 8}, where k >= 1 and 1 <= m <= k. - _Jinyuan Wang_, Mar 24 2020

%e 242 is a member because 229 + (2 + 2 + 9) = 242.
