%N Seven-column table read by rows: Septuples that have the same value of phi, sigma, and tau.

%C The terms are consecutive septuples, ordered so that (A) a(7i-6) < a(7i-5) < ... < a(7i) for i > 0, and (B) a(7i+1) < a(7i+8) for i >= 0.  Primitive solutions are in A322693.

%e 98422632, 98724000, 99373500, 100693920, 101356380, 111298770, and 114002850 have the same value of phi (24883200), sigma (341228160), and tau (192), so these seven numbers are in the sequence.

%Y Cf. A134922, A322692, A322679, A322680, A322681, A322682, A322684, A322685, A322686, A322687.
