Numbers such that Divisor Count divides Phi divides Divisor Sum/Examples/105

Examples of Numbers such that Tau divides Phi divides Sigma
The number $105$ has the property that:
 * $\map \tau {105} \divides \map \phi {105} \divides \map \sigma {105}$

where:
 * $\divides $ denotes divisibility
 * $\tau$ denotes the divisor counting (tau) function
 * $\phi$ denotes the Euler $\phi$ (phi) function
 * $\sigma$ denotes the $\sigma$ (sigma) function.
