Examples of Numbers such that Divisor Count divides Phi divides Divisor Sum
The number $78$ has the property that:
 * $\map {\sigma_0} {78} \divides \map \phi {78} \divides \map {\sigma_1} {78}$

where:
 * $\divides$ denotes divisibility
 * $\sigma_0$ denotes the divisor count function
 * $\phi$ denotes the Euler $\phi$ (phi) function
 * $\sigma_1$ denotes the divisor sum function.
