 OFFSET 1,2 COMMENTS Conjecture: There are infinitely many zeros in this sequence. a(32) = 0 is only a conjecture. If there is a palindromic 5th power, it is greater than 10^40. - David Wasserman, Mar 22 2005 LINKS EXAMPLE 16 = 2^4 which has the prime signature p^4, p a prime; hence a(16) = 14641= 11^4 has the prime signature p^4. a(30) = 66 as 66 and 30 have same prime signature. a(18) = 99, as 44 with the same prime signature is already included as a(12)=44.
