%N Records in A269340.
%C Denote by m(n) the position in A269340 corresponding to a(n). Then m(0)=0, m(1)=1.
%C Conjecture 1. For even n>=2, m(n)=(2/3)*(4^(n-1)-1); for odd n>=3, m(n)=(2/3)*(4^(n-2)-1)+3*4^(n-2).
%C Conjecture 2. For even n>=2, a(n)=2*m(n)+2; for odd n>=3, a(n)=(7*m(n)+12)/11.
%C (Cf. with conjectures in A268866).
%C Sequence {m(n)} begins 0, 1, 2, 14, 42, 234, 682, 3754, 10922, 60074, 174762, 961194, 2796202...
