THE ODD PERFECT PRIME PROBLEM —4th century BCE—

Does an odd perfect prime number exist? A perfect number is one which is equal to the sum of its proper divisors (a divisor other than the number itself). 6 is perfect because 6=1+2+3.

THE TWIN PRIME CONJECTURE —18th century—

Is there an infinite number of twin primes? Two primes are twins if their difference is two.
