%N Numbers n such that the largest digit of n^3 is 5.
%C For any term a(n), all numbers of the form a(n)*10^k, k >= 0, are in this sequence. Primitive terms, i.e., not of this form (or equivalently: without trailing '0'), are 5, 8, 74, 81, 107, 171, 177, 237, 351, 378, 468, 487, 605, 684, 737, 1064, 1271, 1311, 1365, 1474, 1605, 1645, 1724, 1758, ...
%e 8 is in the sequence because the largest digit of 8^3 = 512 is 5.
%o (PARI) for(n=1,2e8, vecmax(digits(n^3))==5&&print1(n","))
%Y Cf. A295025 (the corresponding cubes), A278937 and A294664 (same for digit 3 and 4).
%Y Cf. A000578 (the cubes).
