%N Irregular array read by rows. a(n) is the largest element in the primitive Collatz-like 3x+k cycle associated with A226607(n).
%H Geoffrey H. Morley, <a href="/A226608/b226608.txt">Rows 1..2032 of array, flattened</a>
%e The irregular array starts:
%e (k=1) 1;
%e (k=5) 1, 49, 37, 2772, 3397;
%e (k=7) 11;
%e (k=11) 7, 79;

%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 A226610(n) odd elements.
%Y Cf. A226611, A226624, A226667-A226669.
