In mathematics, prime numbers are fundamental building blocks. They are natural numbers greater than 1 that have no positive divisors other than 1 and themselves. The study of prime numbers, known as number theory, has a rich history and continues to be an active area of research, with applications in cryptography and computer science. The distribution and properties of prime numbers, such as whether they occur infinitely often and how they are spaced, are subjects of ongoing investigation. Palindromic primes, like 25277, represent a specific subset of these numbers with an interesting aesthetic quality.
