It is sufficient to prove the theorem for every odd prime number p. This immediately follows from Euler's four-square identity (and from the fact that the theorem is true for the numbers 1 and 2). The residues of a 2 modulo p are distinct for every a between 0 and ( p − 1)/2 (inclusive).
For example, when d=4, the hash table for two occurrences of d would contain the key-value pair 8 and 4+4, and the one for three occurrences, the key-value pair 2 and (4+4)/4 (strings shown in bold). The task is then reduced to recursively computing these hash tables for increasing n , starting from n=1 and continuing up to e.g. n=4.
Combinations and permutations in the mathematical sense are described in several articles.

In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: n 4 = n × n × n × n. Fourth powers are also formed by multiplying a number by its cube. Furthermore, they are squares of squares.

0 is a multiple of every number (=). The product of any integer n {\displaystyle n} and any integer is a multiple of n {\displaystyle n} . In particular, n {\displaystyle n} , which is equal to n × 1 {\displaystyle n\times 1} , is a multiple of n {\displaystyle n} (every integer is a multiple of itself), since 1 is an integer.
