A291639 Numbers k such that 0 is the smallest decimal digit of k^3. 7

COMMENTS

The sequence is infinite. For example, A062397(i) is in the sequence for any i > 1, since A168575(i) contains the digit 0 for any i > 1. - Felix Fröhlich, Aug 28 2017

Also contains A008592, and has asymptotic density 1. - Robert Israel, Aug 29 2017

EXAMPLE

16 is in the sequence because 16^3 = 4096, the smallest decimal digit of which is 0.

MAPLE

select(n -> min(convert(n^3, base, 10))=0, [$1..1000]); # Robert Israel, Aug 29 2017

PROG

(PARI) select(k->vecmin(digits(k^3))==0, vector(500, k, k))
