 OFFSET 1,1 LINKS EXAMPLE The first exactly-4 terms between successive zeros in A217564 are '1,1,1,1' beginning at index 21, so a(4) = prime(21) = 73. The first exactly-5 terms between successive zeros in A217564 are '2,1,1,1,1' beginning at index 99, so a(5) = prime(99) = 523. CROSSREFS Cf. A217564.
