COMMENTS

The terms are consecutive 11-tuples, ordered so that (A) a(11i-10) < a(11i-9) < ... < a(11i) for i > 0, and (B) a(11i+1) < a(11i+12) for i >= 0. This sequence has primitive solutions only. If k is relatively prime to all of the terms in a primitive 11-tuple, then multiplying the terms in that 11-tuple by k gives another solution - see A322687.

EXAMPLE
|
5701466232, 5806935288, 5824716000, 5863036500, 5940941280, 5978840580, 5980026420, 6376872150, 6520948434, 6566627430, and 6726168150 have the same value of phi (1443225600), sigma (20473689600), and tau (384), so these eleven numbers are in the sequence.
