Error in A031435

[franktaw at netscape.net]

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