Integers for which Divisor Sum of Phi equals Divisor Sum

Theorem
The following positive integers have the property that the $\sigma$ value of their Euler $\phi$ value equals their $\sigma$ value:
 * $\sigma \left({\phi \left({n}\right)}\right) = \sigma \left({n}\right)$


 * $1, 87, 362, 1257, 1798, 5002, 9374, \ldots$
