%N A079730 Kolakoski variation using (1,2,3,4) starting with 1,2.
%C A079730 a(1)=1 then a(n) is the length of n-th run. This kind of Kolakoski variation 
               using(1,2,3,4,...,m) as m grows reaches the Golomb's sequence A001462.
%F A079730 Partial sum sequence is expected to be asymptotic to 5/2*n.
%e A079730 Sequence begins: 1,2,2,3,3,4,4,4,1,1,1,2,2,2,2,3,3,3,3, read it as: (1),
               (2,2),(3,3),(4,4,4),(1,1,1),(2,2,2,2),(3,3,3,3),... then count the 
               terms in parentheses to get: 1,2,2,3,3,4,4,.. which is the same sequence.
%Y A079730 Cf. A000002.
