Why should we be thinking about perfect numbers today? If theres any day of the year on which we should contemplate the perfect number, today is the day, since its the only date on which both parts of the date  6 and 28  are different perfect numbers. A perfect number is a number equal to the sum of its divisors, including 1 but excluding itself. Thus, 6 is the first perfect number, since it equals 1+2+3. The next one is 28, which equals 1+2+4+7+14. After that come 496 and 8,128. So far, 47 perfect numbers have been identified by mathematicians, of which the largest is 243,112,608 × (243,112,609&#8722;1), discovered in 2001. Some open questions include: Are there infinitely many perfect numbers? and Are there any odd perfect numbers?
