Number of primes equal to the difference of two consecutive eleventh powers (x+1)^11 - x^11 = 11x(x+1)(x^2+x+1)(x(x+1)(x^2+x+1)(x^2+x+3)+1) +1 (A189055). Values of x = A211184. Sequence of number of primes of the form (x+1)^7 - x^7 with x <= 10^n have similar characteristics to similar sequences for natural primes, cuban primes (A221794) and primes of the form (x+1)^p - x^p for p = 5 (A221849) and p = 7 (A221980).
