COMMENTS
| This is the probability that three randomly chosen integers are relatively prime (cf. A018805). - Gary McGuire, Dec 13 2004
This is also the probability that a random integer is cube-free. - Eugene Salamin, Dec 13 2004
On the other hand, the probability that three randomly-chosen integers are pairwise relatively prime is given by A065473. [Charles R Greathouse IV, Nov 14 2011]
