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)
The super-Poulet numbers below 10,000 are :

''n''
1	341 = 11 × 31
2	1387 = 19 × 73
3	2047 = 23 × 89
4	2701 = 37 × 73
5	3277 = 29 × 112
6	4033 = 37 × 109
7	4369 = 17 × 257
8	4681 = 31 × 151
9	5461 = 43 × 127
10	7957 = 73 × 109
11	8321 = 53 × 157

super-poulet numbers with 3 or more distinct prime divisors

It is relatively easy to get super-poulet numbers with 3 distinct prime divisors. If you find three poulet numbers with three common prime factors, you get a super-poulet number, as you built the product of the three prime factors.
Example:
2701 = 37
★ 73 is a poulet number
4033 = 37
★ 109 is a poulet number
7957 = 73
★ 109 is a poulet number
so 294409 = 37
★ 73
★ 109 is a poulet number too.
Super-poulet numbers with up to 7 distinct prime factors you can get with the following numbers:

★ { 103, 307, 2143, 2857, 6529, 11119, 131071 }

★ { 709, 2833, 3541, 12037, 31153, 174877, 184081 }

★ { 1861, 5581, 11161, 26041, 37201, 87421, 102301 }

★ { 6421, 12841, 51361, 57781, 115561, 192601, 205441 }
For example 1.118.863.200.025.063.181.061.994.266.818.401 = 6421
★ 12841
★ 51361
★ 57781
★ 115561
★ 192601
★ 205441 is a super-poulet number with 7 distinct prime factors and 120 Poulet numbers.
