A330959 - cp's OEIS frontend

A330959 For any n >= 0: consider all pairs of numbers (x, y) whose binary representations can be interleaved (or shuffled) to produce the binary representation of n (possibly with leading zeros); a(n) is the least possible value of x XOR y (where XOR denotes the bitwise XOR operator).
