194

Number
$194$ (one hundred and ninety-four) is:


 * $2 \times 97$


 * The $28$th nontotient:
 * $\nexists m \in \Z_{>0}: \phi \left({m}\right) = 194$
 * where $\phi \left({m}\right)$ denotes the Euler $\phi$ function


 * The $6$th positive integer solution after $1, 3, 15, 104, 164$ to $\phi \left({n}\right) = \phi \left({n + 1}\right)$:
 * $\phi \left({194}\right) = 96 = \phi \left({195}\right)$
