FORMULA
|
A prime index is the numerical position of a prime number in the sequence of prime numbers. A Prime-Index-Prime (PIP) is a prime number whose index is also prime. A Prime-Index-Prime rectangle is a rectangle whose sides are components of Prime-Index-Primes.
|
|
|
EXAMPLE
|
The second set of consecutive PIPs, 5 and 11, produce a 5x11 unit rectangle whose area is 55 square units.
