Table errata 2 to "Factors of generalized Fermat numbers"

We note that three factors are missing from Table 1 in Factors of generalized Fermat numbers by A. Björn and H. Riesel published in Math. Comp. 67 (1998), 441–446. In Table 1 in Björn–Riesel [2] there are unfortunately three factors missing. Fougeron [3] discovered that 31246291 · 2 + 1 ∣ ∣ 11 51 + 1 and 33797295 · 2 + 1 ∣ ∣ 10 62 + 3 62 . He also verified that no other factors are missing for 30 ≤ n ≤ 703, given the search ranges mentioned in [2]. M. Schroeder [4] and later N. S. de Araújo Melo [1] discovered that 3 · 2 +1 is a prime. This number is missing in the list of primes given in Young [5], a list which had kindly been made available to us when we wrote [2] and which we used without checking. This number is therefore also missing in Table 1 in [2]. The number 3 · 2 + 1 is a factor in 3 54787 + 1, 5 54786 + 1, 5 54787 + 3 54787 , 7 54790 + 1, 7 54790 + 3 54790 , 7 54790 + 5 54790 , 4 54790 − 2254790 + 1, 8254790 + 3254790 , 8 54790 + 5 54790 , 8 54787 + 7 54787 , 9 54785 + 5 54785 , 9 54790 + 7 54790 , 9 54790 + 8 54790 , 11 54791 + 2 54791 , 11 54791 + 6 54791 and 11 54791 + 10 54791 .
