Table of n, a(n) for n=1..58.

16 does not contain a 0 and 16^3 = 4096 contains a 0. Thus, 16 is a member of this sequence.

(Python)

{print(n) for n in range(10**3) if str(n).count("0")==0 and str(n**3).count("0")>0}

(PARI) is(n)=Set(digits(n))[1] && Set(digits(n^3))[1]==0 \\ Charles R Greathouse IV, Jul 10 2015
