Examples of Numbers such that Tau divides Phi divides Sigma
The number $140$ has the property that:
 * $\map \tau {140} \divides \map \phi {140} \divides \map \sigma {140}$

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