1,1
Table of n, a(n) for n=1..12.
(2^3-1)-(2^2-1)-1 = 5 = Mersenne-prime(2)-Mersenne-prime(1)-1 k=2 j=1 for n=1
(2^5-1)-(2^3-1)-1 = 23 = Mersenne-prime(3)-Mersenne-prime(2)-1 k=3 j=2 for n=2
(2^17-1)-(2^3-1)-1 = 131063 = Mersenne-prime(6)-Mersenne-prime(2)-1 k=6 j=2 for n=3
and 3,23,131063 are primes
