Albert Lau: ok so it looks fine. 210694 because it took 5 second on my computer to generate. that page says as long as no number exceeds 1000 digits, so i presume 210694 is ok?

02:52

Michel Marcus: I think you will rarely find b-files with more than 10000 terms.

Joerg Arndt: "210694 because it took 5 second on my computer to generate"  this means that downloading is hardly worth it!  Suggest to cut down to 10k

This is also the list of a, where a is positive integer solutions of 1/a+1/b=1/c and a>b>c and gcd[a,b,c]=1, sorted by ascending a, then b. See A247372 for list of b, A246429 for list of c. - _Albert Lau_, Sep 19 2014

Michel Marcus: Signatures are fine.
Just a note, when for a program, then it is commented out depending on language syntax
