202

Number
$202$ (two hundred and two) is:


 * $2 \times 101$


 * The $29$th nontotient:
 * $\nexists m \in \Z_{>0}: \phi \left({m}\right) = 202$
 * where $\phi \left({m}\right)$ denotes the Euler $\phi$ function


 * The $18$th noncototient after $10$, $26$, $34$, $50$, $52$, $58$, $86$, $100$, $116$, $122$, $130$, $134$, $146$, $154$, $170$, $172$, $186$:
 * $\nexists m \in \Z_{>0}: m - \phi \left({m}\right) = 202$
 * where $\phi \left({m}\right)$ denotes the Euler $\phi$ function


 * The $2$nd positive integer after $200$ that cannot be made into a prime number by changing just $1$ digit


 * The $9$th Smith number after $4$, $22$, $27$, $58$, $85$, $94$, $121$, $166$:
 * $2 + 0 + 2 = 2 + 1 + 0 + 1 = 4$
