SUMMARY
The discussion centers on proving that either the intersection of the sequences [a]_{n} and [b]_{n} is empty or the two sequences are equal. The user attempts to demonstrate that if an element x exists in both sequences, it leads to the conclusion that [a]_{n} must equal [b]_{n}. The proof hinges on the modular relationships defined by x, specifically that if x is congruent to a modulo n and b modulo n, then the difference a-b must equal zero, confirming the equality of the sequences.
