%N A322695 Nine-column table read by rows: Primitive distinct 9-tuples that have the same value of phi, sigma, and tau.
%C A322695 The terms are consecutive 9-tuples, ordered so that (A) a(9i-8) < a(9i-7) < ... < a(9i) for i > 0, and (B) a(9i+1) < a(9i+10) for i >= 0.  This sequence has primitive solutions only.  If k is relatively prime to all the terms in a primitive 9-tuple, then multiplying the terms in that 9-tuple by k gives another solution - see A322685.
