 A135066 Primes p such that p^3 is a palindrome. 1
 2, 7, 11, 101 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS Note that all first 4 listed terms are the palindromes. Corresponding palindromic cubes a(n)^3 are listed in A135067 = {8, 343, 1331, 1030301, ...}. PrimePi[ a(n) ] = {1, 4, 5, 26, ...}. LINKS P. De Geest, Palindromic Cubes FORMULA a(n) = A135067(n)^(1/3). EXAMPLE a(3) = 11 because 11^3 = 1331 is a palindrome. MATHEMATICA Do[ p = Prime[n]; f = p^3; If[ f == FromDigits[ Reverse[ IntegerDigits[ f ] ] ], Print[ {n, p, f} ]], {n, 1, 200000} ] CROSSREFS Cf. A002780 = Cube is a palindrome. Cf. A069748 = Numbers n such that n and n^3 are both palindromes. Cf. A002781 = Palindromic cubes. Cf. A135067 = Palindromic cubes p^3, where p is a prime.
