It is a nontotient since there is no integer with exactly 122 coprimes below it. Nor is there an integer with exactly 122 integers with common factors below it, making 122 a noncototient. (*In number theory, a nontotientis a positive integer n which is not a totient number: it is not in the range of Euler’s totient function φ, that is, the equation φ(x) = n has no solution x. In other words, n is a nontotient if there is no integer x that has exactly ncoprimes below it. All odd numbers are nontotients, except 1, since it has the solutions x = 1 and x = 2.)*
