FORMULA

For all k>2:

a(A000295(k)) = a(A000295(k+1)) = 3;

For A000295(k)<n<2^k-2, a(n) = a(n+2^k-1) = a(n+2^(k+1)-1);

For n = 2^k-2, a(n) = a(n+2^(k+1)-1), a(2^(k+1)-2) = a(n)+5*3^(k-2);

a(2^(k+1)-3) = 4*3^(k-2);

For 2^k-2<n<A079583(k-1)-1, a(n) = a(n+2^k)=a(n+2^(k+1)-1);

For n = A079583(k-1)-1, a(n) = a(n+2^(k+1)-1) = 1;

For n = A079583(k-1), a(n) = a(n+2^(k+1)-1) = 2;

a(A079583(k-1)+2^k-1) = 3;

For A079583(k-1)<n<A000295(k+1), a(n) = a(n+2^k-1) = a(n+2^(k+1)-1)
