Highly deficient number[edit]

Let's define deficient number as σ(n)<2n and highly deficient number as σ(n)<1.5n — Preceding unsigned comment added by (talk)

Wikipedia does not make up definitions. Our articles must be verifiable, based on reliable published sources. I cannot find your suggested definiton in a Google search. PrimeHunter (talk) 13:34, 11 July 2014 (UTC)
