%N The smallest palindromic prime which contains the decimal expansion of 11^n in its decimal representation.
%C The entries have two possible formats: a//11^n ( = 11^n//b), where the double-slash denotes concatenation, or c//11^n//d.
%C By definition, the concatenation has to be a palindromic prime, A002385.
%e a(0) = 11^0//1 = 1//1 = palprime(5).
%e a(1) = 11^1 = 11.
%e a(2) = 1212//11^2 = 1212//121 = palprime(151).
%e a(3) = 13311//11^3 = 13311//1331 = palprime(1270).
%e a(4) = 36//11^4//63 = 36//14641//63 = palprime(3035).
%e a(5) = 3150//11^5//3 = 3150//161051//3 = palprime(18465).
%e a(6) = 9165177//11^6//9 = 9165177//1771561//9.
%e a(7) = 101717849//11^7//01 = 101717849//19487171//01.
