%N Nine-column table read by rows: 9-tuples that have the same value of phi, sigma, and tau.

%C 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. The primitive solutions are in A322995.

%e 4337267040, 4548689376, 4577446560, 4578614964, 4606647660, 4607561340, 5024337318, 5056654590, and 5059532610 have the same value of phi (1106472960), sigma (15850598400), and tau (384), so these nine numbers are in the sequence.

%Y Cf. A134922, A322692, A322679, A322680, A322681, A322682, A322683, A322684, A322686, A322687.
