For any term a(n), all numbers of the form a(n)*10^k, k >= 0, are in this sequence. We could call "primitive" the terms not of this form, i.e., without trailing '0'.
Includes a*10^k+b for k >= 3 and [a,b] in {[11, 1], [5, 4], [4, 5], [6, 5], [5, 6], [11, 10], [1, 11], [10, 11]}, and 8*10^k+8 for k >= 4. - Robert Israel, Jul 22 2019

EXAMPLE
4 is in the sequence because the largest digit of 4^3 = 64 is 6.
PROG
(PARI) for(n=1, 2e3, vecmax(digits(n^3))==6&&print1(n", "))
