COMMENTS

For any term a(n), all numbers of the form a(n)*10^3k, k >= 0, are in this sequence. We could call "primitive" the terms not of this form, i.e., those without trailing '0'.

LINKS

Table of n, a(n) for n=1..36.

FORMULA

a(n) = A294998(n)^3.

EXAMPLE

8 is in the sequence because it is a cube, 8 = 2^3, and its largest digit is 8.

PROG

(PARI) for(n=1, 200, vecmax(digits(n^3))==8 &&print1(n^3, ", "))
