A positive integer p is called a prime, if p has exactly two different positive divisors. Every prime p is thus greater than 1 and it is divisible by itself and 1. Positive integers greater than 1 are called composite if they are not primes.

Elemental Complete Composite Number Generators
The Fibonacci quarterly, 1985Proof: It suffices to produce an example of such a function. Here, the existence of several such functions will be shown. First, consider the following two sequences: 2, 3, 3, 4, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, ...

On Highly Composite Numbers [PDF]
Journal of the London Mathematical Society, 1944 for a certain c. In fact I shall prove that if n is highly composite, then the next highly composite number is less than n+n(log y&)-C ; and the result just stated follows immediately from this. At, present I cannot, decide whether the number of highly composite numbers not exceeding z is greater than (logx)” for every k.

The win ratio approach for composite endpoints: practical guidance based on previous experience.
European Heart Journal, 2020The win ratio was introduced in 2012 as a new method for examining composite endpoints and has since been widely adopted in cardiovascular (CV) trials.

An asymptotic formula for the nth composite number C n , with an error term O(n/log m n) for any fixed m, is given. Exact calculations for C n with various n ≤ 1013 are also given, showing that approximations to C n by the asymptotic formula have errors ...
