“…These numbers expressed in binary representation are n + 2 bits long being "10" by n 1's. Thabit ibn Qurra was the first to study these numbers and their relation to amicable numbers (see [5]). He discovered and proved that if p = 3.2 n − 1, q = 3.2 n−1 − 1 and r = 9.2 n−1 − 1 are prime numbers, then M = 2 n pq and N = 2 n r are a pair of amicable numbers.…”
