Super-Poulet number

A super-Poulet number is a Poulet number whose every divisor d divides 2^d - 2. For example 341 is a super-Poulet number: it has positive divisors {1, 11, 31, 341} and we have:

(2¹¹ - 2) / 11 = 2046 / 11 = 186

(2³¹ - 2) / 31 = 2147483646 / 31 = 69273666

(2³⁴¹ - 2) / 341 = ... (an integer)
