%N Composite Beatty sequence of sqrt(3).
%C The bisection (3,12,48,...) is a subsequence of A022838.
%C The bisection (2,7,28,...) is a subsequence of A054406.
%C See the comment at A107857 regarding Beatty sequences.
%F a(n)=floor(s*a(n-1)) if n odd, a(n)=floor(r*a(n-1)) if n even, where r=sqrt(3), s=(r+3)/2, a(1)=floor(s).
%Y Cf. A022838, A054406, A107857, A182631.
