Compare with A108618. Beginning at a(16350) = 560, the sequence apparently enters a loop and repeats the 60 terms: 560, 382, 327, 503, 558, 383, 328, 503, 557, 383, 327, 504, 558, 382, 327, 504, 560, 381, 327, 506, 559, 380, 327, 507, 559, 377, 326, 508, 558, 377, 328, 508, 559, 377, 326, 509, 560, 377, 325, 509, 559, 378, 326, 508, 559, 378, 328, 507, 559, 380, 327, 506, 559, 381, 327, 503, 558, 382, 326, 503.
Let f(n) give the frequency of occurance of the number n in the above 60 term set. Then f(560) = 3, f(382) = 3, f(327) = 7, f(503) = 4, f(558) = 4, f(383) = 2, f(328) = 3, f(557) = 1, f(504) = 2, f(381) = 2, f(506) = 2, f(559) = 7, f(380) = 2, f(507) = 2, f(377) = 4, f(326) = 4, f(508) = 3, f(509) = 2, f(325) = 1, f(378) = 2
