%N A092860 "3 times the prime sequence".
%C A092860 By iterating the addition to itself a monotonic sequence, according to 
               the definition given in A092858, we can multiply the monotonic sequences 
               by natural numbers.
%C A092860 Note, that it is easy to see that for an i natural and a v monotonic 
               sequence, i(x)compl(v)=compl(i(x)v); where the "(x)" mark stands 
               for the "integer multiplication of a sequence" and the function "compl" 
               produces the complement of a positive monotonic sequence.
