%F a(n) = MMDDYY_date('Mar 1 00' + A210894(n)).

%e The first palindromic date in MMDDYY format after 'Jan 01 00' is a(1)=101101 (= 'Oct 11 01' = 'Mar 01 00' + A210894(1) days);

%e The third palindromic date in MMDDYY format after 'Jan 01 00' is a(3)=11110=011110 (= 'Jan 11 10' = 'Mar 01 00' + A210894(3) days);

%e The 10th palindromic date in MMDDYY format after 'Jan 01 00' is a(10)=122221 (= 'Dec 22 21' = 'Mar 01 00' + A210894(10) days).

%e The last (24th) palindromic date in MMDDYY format after 'Jan 01 00' is a(24)=92290=092290 (= 'Sep 22 90' = 'Mar 01 00' + A210894(24) days).
