On Highly Composite and Similar Numbers [PDF]

open access: yesTransactions of the American Mathematical Society, 1944
A (positive whole) number is called highly composite if it has more divisors than any smaller number, highly abundant if the sum of its divisors is greater than that for any smaller number, and superabundant if the sum of the reciprocals of its divisors is greater than that for any smaller number. The author uses \textit{A. E.
