Havil 2003, p. 171 The distribution of primes in the large, such as the question how many primes are smaller than a given, large threshold, is described by the prime number theorem, but no efficient formula for the n-th prime is known.
The n-th order intermodulation products then appear at n times the frequency spacing of the input tones.
Thus for finite n, the expression "n-th element" of a well-ordered set requires context to know whether this counts from zero or one.
In general an n-th order will lead to n+1-th wave mixing.
Note that the n-th generation can be found by just taking the n-th power of W substituting it in place of W in the above formula.
