%N Numbers which are palindromic in their Elias delta code representation.

%C Number n, such that A281150(n) is palindromic.

%H Indranil Ghosh, <a href="/A281380/b281380.txt">Table of n, a(n) for n = 1..1012</a>

%e 43 is in the sequence because Elias delta code for 43 is '1101001011' and '1101001011' is palindromic.

%o (Python)

%o i=1

%o j=1
