单词 QuasiperfectNumber
释义

quasiperfect number


If there exists an abundant number n with divisorsMathworldPlanetmathPlanetmath d1,,dk, such that

i=1kdi=2n+1,

that number would be called a quasiperfect number. Such a number would be n>1035 and have ω(n)>6 (where ω is the number of distinct prime factors function).

A quasiperfect number would thus overshoot the mark for being a perfect number by a margin of just 1. (The powers of 2 are short of perfection by a margin of 1).
