%N Numbers m such that the digits of m are also digits of m^3.

%C Presumably if a digit d appears k times in m, then it should appear at least k times in m^3. - _N. J. A. Sloane_, Nov 24 2018

%e 12^3 = 1728, which contains all digits of 12, so 12 is a term of the sequence.

%t Select[Range[400],Min[DigitCount[#^3]-DigitCount[#]]>-1&] (* _Harvey P. Dale_, Nov 24 2018 *)

%Y Cf. A029776.
