Table of n, a(n) for n=1..32.

EXAMPLE

The prime 7219 is in the list because 2197 = 13*13*13.

PROG

(PARI) rotl(a) = my(b, c, d); b=#Str(a); c=floor(a/(10^(b-1))); d=a-c*(10^(b-1)); 10*d+c

s=[]; forprime(n=2, 40000000, if(ispower(rotl(n), 3), s=concat(s, n))); s

(Sage)

[i for i in primes_first_n(1000000) if Integer((int(str(i)[1:]+str(i)[:1]))).nth_root(3, True)[1]] # Tom Edgar, Jan 03 2014
