%N Irregular array read by rows. a(n) is the number of odd elements in the primitive Collatz-like 3x-k cycle associated with A226623(n).
%H Geoffrey H. Morley, <a href="/A226626/b226626.txt">Rows 1..280 of array, flattened</a>
%e The irregular array starts:
%e (k=1) 1, 2, 7;
%e (k=11) 3;
%e (k=17) 4, 4;
%e (k=19) 11;
%e a(4)=3 is the number of odd elements in the 3x-11 cycle {19,23,29,38} associated with A226623(4)=19
%Y Row n begins with a(A226628(n)) and has length A226629(n). k=A226630(n).
%Y The cycle associated with a(n) has length A226625(n) and its largest element is A226624(n).
%Y Cf. A226610, A226627, A226632, A226689.
