I think that the webmaster did not write the relation of divisiblity between A0 and A1 because the question was to find a sequence of triplets with the conditions quoted 1 to 4 ”and the A0 A1 are simply to explain the goal of the question.
Sorry, in my answer, I meant if A0 and A1 are not coprime then the sequence would be trivial.
