%N 'Erratic' numbers in A064353 [Kolakoski (1,3)]
%C A064353(n) is generally 1 if n is odd and 3 if n is even. An 'erratic' number breaks this rule.
%H Reinhard Zumkeller, <a href="/A146562/b146562.txt">Table of n, a(n) for n = 1..10000</a>
%e A064353(3) is predicted to be 1 but is 3 so 3 is in the list.
