(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A135047 Initial members of an octuplet of generalized Fermat primes: numbers n such that (n+m)^4+1 is prime for m=0,2,4,6,8,10,12 and 14. 0
10332305196, 15731023654, 202193785336, 417860702688, 427241399860, 648488931216 (list; graph; refs; listen; history; text; internal format)

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.
