Numbers such that Divisor Count divides Phi divides Divisor Sum/Examples/3

Examples of Numbers such that Divisor Count divides Phi divides Divisor Sum
The number $3$ has the property that:
 * $\map {\sigma_0} 3 \divides \map \phi 3 \divides \map {\sigma_1} 3$

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