%F A prime index is the numerical position of a prime number in the sequence of prime numbers. A Prime-Indexed Prime (PIP) is a prime number whose index is also prime. A Prime-Indexed Prime rectangle is a rectangle whose sides are components of Prime-Indexed Primes.

%e The second set of consecutive PIPs, 5 and 11, produce a 5 X 11 unit rectangle whose area is 55 square units.
