<DIV> Sequence A031435 has the formula a(n) = ceiling((n+1/2)*log(n)). This formula is not (quite) correct; the first discrepancy is n = 78, where the formula gives the value 343, but the correct value is 342. The formula is also wrong for n = 214; there are no other errors up to 1000.</DIV>

<DIV>This error affects the PARI program in the entry as well. However, it is beyond the actual values shown, which are all correct.</DIV>
