• Minimal Thompson primes: a(n) is the smallest prime expressible as p1*p2*...*pk-q1*q2*...*qj, where k+j=n and {p1,...,qj} are the first n primes.at n=18A060772
• Write product of first n primes as x*y with x<y and x maximal; sequence gives value of y-x.at n=20A061060
• a(n) = min(p +- q) > 1 with p*q being equal to the n-th primorial (A002110).at n=18A246463
