COMMENTS

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.

EXAMPLE
|
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.
