# 9719

This number is a prime.

The largest four digit prime in which the first, second and third pairs of digits are prime (97,71,19) and the first and second three digits (971,719) are also prime. [McGrath]

In the 2006 movie "Snakes on a Plane," the air traffic controller's display shows the aircraft DMA 134 at 9719 feet. Controllers' readouts actually only show the altitudes to the nearest hundred feet. [Caldwell]

The only canyon prime concatenated from two double-digit primes. [Loungrides]
