134
134 is a nontotient since there is no integer with exactly 134 coprimes below it. And it is a noncototient since there is no integer with 134 integers with common factors below it.
134 is 8 C 1 + 8 C 3 + 8 C 4 {\displaystyle {}_{8}C_{1}+{}_{8}C_{3}+{}_{8}C_{4}} {}_8C_1 + {}_8C_3 + {}_8C_4.
In Roman numerals, 134 is a Friedman number since CXXXIV = XV * (XC/X) - I.
