%N A105473 First "Fractal Jump Sequence" (FJS) having its first nine digits different 
               one from another, then the next nine, then the next nine, etc.
%C A105473 An FJS is a sequence of digits embedding an infinite amount of copies 
               of itself. Modus operandi: underline the first digit "a" of such 
               a sequence then jump over the next "a" digits and underline the digit 
               "b" on which you land. Jump now from there over the next "b" digits 
               and underline the digit "c" on which you land. And so on. The "abc...n..." 
               succession of underlined digits is the sequence itself.
