What are the perfect numbers between 1 and 1000?

Around 100 c.e., Nicomachus noted that perfect numbers strike a harmony between the extremes of excess and deficiency (as when the sum of a number's divisors is too large or small), and fall in the “suitable” order: 6, 28, 496, and 8128 are the only perfect numbers in the intervals between 1, 10, 100, 1000, 10000, and ...
