%N a(n) is the largest number such that all of a(n)'s length-n substrings are distinct and divisible by 34.
%H Hans Havermann, <a href="/A093211/a093211.txt">Table of A093211-A093299</a>
%e a(3) is 30680 because its length-3 substrings (306, 068, 680) are all distinct and divisible by 34 and there is no larger number with this property.
