%N Zeroless numbers n such that n^3 contains a 0.

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

%o (Python)

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

%o (PARI) is(n)=Set(digits(n))[1] && Set(digits(n^3))[1]==0 \\ _Charles R Greathouse IV_, Jul 10 2015

%Y Subsequence of A242214.

%Y Cf. A052382 (zeroless numbers), A134843.
