What's more, 4n+1 prime or composite numbers are given as the sum or difference of two squares respectively.

PrimeCalculator also classifies a number as perfect, abundance or deficient and display its perfect, abundance or deficient index and allows the user to enter an index to go directly to a perfect, an abundance or a deficient number by index.
