For the first 10 terms we have a(n) = n^2 * a(1). Are there any other primitive terms other than a(1)?

			These 6 triples have a common difference of 9309396096000: (579774^2, 3105726^2, 4353726^2), (781560^2, 3149640^2, 4385160^2), (2241720^2, 3786120^2, 4862520^2), (4187880^2, 5181480^2, 6013080^2), (9320040^2, 9806760^2, 10270440^2), and (10273140^2, 10716660^2, 11142540^2).
