 10332305196, 15731023654, 202193785336, 417860702688, 427241399860, 648488931216 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS n^4+1 can be prime for at most eight consecutive even numbers n, otherwise at least one member would be divisible by 17. LINKS Table of n, a(n) for n=1..6. EXAMPLE a(1)=10332305196 because 103323051964^4+1 is prime and (10332305196+m)^4+1 is prime for all even m up to 14. CROSSREFS Cf. A000068.
