### When n is a power of 2

I'm not so sure this is correct for powers of 2. For example, 8. Totatives are 1, 3, 5, 7; divisors are 1, 2, 4, 8. The union of these two sets if 1, 2, 3, 4, 5, 7, 8; missing is 6.

### Re: When n is a power of 2

Good catch. Obviously, 6 is not a divisor of any power of 2. I'll edit accordingly. Thanks.
