A240589 Primes of the form (n + 2)^n + 2. 1
3, 5, 127, 4782971, 2357947693 (list; graph; refs; listen; history; text; internal format)
OFFSET

1,1

LINKS

Table of n, a(n) for n=1..5.

EXAMPLE

3 is in this sequence because (0+2)^0+2 = 1 + 2 = 3 for n = 0,

5 is in this sequence because (1+2)^1+2 = 3 + 2 = 5 for n = 1,

127  is in this sequence because (3+2)^3+2 = 125 + 2 = 127 for n = 3.

PROG

(MAGMA) [a: n in [0..9] | IsPrime(a) where a is (n+2)^n+2];
