The value 2 n   &minus   n or n   &minus   s n is called the number s deficiency .

Its divisors are 1, 3, 7 and 21, and their sum is 32. Because 32 is less than 2    21, the number 21 is deficient. Its deficiency is 2    21  &minus   32    10. Properties An infinite number of both even and odd numbers even and odd deficient numbers exist All odd numbers with one or two distinct prime factors are deficient All proper divisor s of deficient or perfect number s are deficient. Related Concepts Closely related to deficient numbers are perfect number s with n     2 n , and abundant number s with n     2 n . The natural number s were first classified as either deficient, perfect or abundant by Nicomachus in his Introductio Arithmetica circa 100 .

It is most notable for being a perfect number , and one of the earliest numbers to be recognized as such. As a perfect number, it is tied to the Mersenne prime 127 number 127 , 2 sup 7 sup 1, with 2 sup 6 sup 2 sup 7 sup 1 yielding 8128. Also related to its being a perfect number, 8128 is a harmonic divisor number . Another consequence of 8128 being a perfect number is that it has the same prime factors as the sum of its divisors, its cototient is a power of two, and it is a harmonic seed number though there are deficient and abundant numbers that share these properties . 8128 is the 127th triangular number , the 64th hexagonal number , a happy number , the eighth 292 gonal number , and the fourth 1356 gonal number, as well as the 43rd centered nonagonal number .
