%N Irregular array read by rows. a(n) is the number of odd elements in the primitive 3x+k cycle associated with A226607(n).

%H Geoffrey H. Morley, <a href="/A226610/b226610.txt">Rows 1..2032 of array, flattened</a>

%e The irregular array starts:

%e (k=1) 1;

%e (k=5) 1, 3, 3, 17, 17;

%e (k=7) 2;

%e (k=11) 2, 8;

%e a(2)=1 is the number of odd elements in the 3x+5 cycle {1,4,2} associated with A226607(2)=1.

%Y Row n begins with a(A226612(n)) and has length A226613(n).

%Y The cycle associated with a(n) has length A226609(n) and its largest element is A226608(n).

%Y Cf. A226611, A226626.
