%N Squares in every base >=3 (involving no carries and no digit apart from 0, 1 and 2).
%C The reverse of every element in the list is also in the list.
%C Concatenated coefficients of polynomial squares where all coefficients in the square are 0, 1, or 2. - _Franklin T. Adams-Watters_, Mar 12 2006
%e 10100^2 = 102010000 is in the list but 10101^2 = 102030201 (if working in bases >=4) or = 102100201 (if working in base 3) is not.
