Values of x = A121619 - 1. Number of primes equal (x+1)^7 - x^7 < 10^(n) in A221977. Partial sums of number of primes of the form (x+1)^7 - x^7 have similar characteristics to similar sequences for natural primes (A007504), cuban primes (A221793) and primes of the form (x+1)^5 - x^5 (A221848). %H A221979 Vladimir Pletser, <a href="/A221979/b221979.txt">Table of n, a(n) for n = 1..1000</a> %t A221979 Accumulate[Select[Differences[Range[80]^7],PrimeQ]] (* _Harvey P.
