%N Numbers n not divisible by 10 such that n^3 contains at least one 0.

%C n^3 may contain one or more zeros. - _Harvey P. Dale_, Oct 03 2016

%H Harvey P. Dale, <a href="/A242214/b242214.txt">Table of n, a(n) for n = 1..2500</a>

%e 16 is not divisible by 10 and 16^3 = 4096, which contains a 0. Thus, 16 is a member of this sequence.

%t Select[Range[200],Mod[#,10]!=0&&DigitCount[#^3,10,0]>0&] (* _Harvey P. Dale_, Oct 03 2016 *)

%o (Python)

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

%o (PARI) isok(n) = (n % 10) && (vecmin(digits(n^3)) == 0); \\ _Michel Marcus_, May 10 2014
