%N Positions in A213728 and A213729 where the next record length run starts.
%C A218545(A218546(n)) gives the records (of run lengths), which for the first five cases are: 1, 2, 4, 6, 8.
%C A213729(a(n)) gives the parity of the n-th record run, which for the first case (n=1) is 0, and for the next four (n=2..5) is 1.
