%N A227410 Palindromic prime numbers representing a date in "condensed American notation" MMDDYY.
%C A227410 For February, the number of days will be 28 only, as the year cannot be a leap year if MMDDYY is to be a prime number.
%C A227410 The sequence is finite, with 27 terms. The largest term is a(27)=91019.
%e A227410 a(1)=10301 is palindromic prime and represents a date in MMDDYY format as 010301.
