EXAMPLE
19 starts a run of 2 consecutive primes 19 and 23, bigomega(19+1) = 2 = omega(19+1) + 1, bigomega(23+1) = 4 = omega(23+1) + 2 and bigomega(29+1) = 3 <> omega(29+1) + 3. So a(2) = 19.
Let i, p, b and w be the indices, the primes p_i, bigomega(p_i + 1) and omega(p_i + 1).
i: [ 1 2 3]
p: [19 23 29]
b: [ 3 4 3]
w: [ 2 2 3]
a(2) = 19
i: [ 1 2 3 4]
p: [739 743 751 757]
b: [ 4 5 5 2]
w: [ 3 3 2 2]
a(3) = 739
