116

Number
$116$ (one hundred and sixteen) is:


 * $2^2 \times 29$


 * The $9$th noncototient after $10, 26, 34, 50, 52, 58, 86, 100$:
 * $\nexists m \in \Z_{>0}: m - \phi \left({m}\right) = 116$
 * where $\phi \left({m}\right)$ denotes the Euler $\phi$ function


 * The $2$nd term of the $2$nd $5$-tuple of consecutive integers have the property that they are not values of the $\sigma$ function $\sigma \left({n}\right)$ for any $n$:
 * $\left({115, 116, 117, 118, 119}\right)$


 * The $1$st of the $4$th pair of consecutive integers which both have $6$ divisors:
 * $\tau \left({116}\right) = \tau \left({117}\right) = 6$
