%N Integers but with the primes cubed.

%H Vincenzo Librandi, <a href="/A282462/b282462.txt">Table of n, a(n) for n = 0..2000</a>

%e a(4) = 4 because 4 is composite.

%e a(5) = 125 because 5 is prime and 5^3 = 125.

%t Join[{0},If[PrimeQ@#,#^3,#]&/@Range@80]

%o (MAGMA) [0] cat [IsPrime(n) select n^3 else n: n in [1..60]];

%Y Cf. A061397, A103164, A143545.
