%N Numbers n for which the cube excess of the n-th prime is prime.
%F n such that A055400(A000040(n)) is an element of A000040. n such that A104492(n) is prime.
%e 99 is an element of this sequence because the 99th prime is 523, 523 - 8^3 = 523-512 = 11 and 11 is prime. 100 is in this sequence because the 100th prime is 541 and 541-8^3 = 29, which is prime.
%t f[n_] := Block[{k = 1, p = Prime[n]}, While[k^3 < p, k++ ]; p - (k - 1)^3]; Select[ Range[ 284], PrimeQ[ f[ # ]] &] (* _Robert G. Wilson v_, Mar 19 2005 *)
