%N Digits are cubes.

%C This is also a sequence where the digits of each integer are both horizontally and vertically symmetrical. - _Philip Mizzi_, May 24 2014

%C Numbers with no prime or semiprime digits. - _Wesley Ivan Hurt_, Jan 17 2016

%C Because the digits of each term can only be 0, 1 or 8, each number in the sequence is both mirror ambigrammatic and rotationally ambigrammatic. - _Philip Mizzi_, Jan 01 2021
