A003188: Decimal equivalent of Gray code for

n

.

{0, 1, 3, 2, 6, 7, 5, 4, 12, 13, 15, 14, 10, 11, 9, 8, 24, 25, 27, 26, 30, 31, 29, ... }

In binary, visits every node of an

n

-cube, by a change of exactly one coordinate (0 to 1, or 1 to 0).
     

a (n) = n XOR n 2 .

     

a (0) = 0; a (n) = 2 a  n 2 + n + 1 2 mod 2, n ≥ 1.
