EXAMPLE
The irregular array starts:
(k=1) 1, 2, 7;
(k=11) 3;
(k=17) 4, 4;
(k=19) 11;
a(4)=3 is the number of odd elements in the 3x-11 cycle {19,23,29,38} associated with A226623(4)=19
CROSSREFS
Row n begins with a(A226628(n)) and has length A226629(n). k=A226630(n).
The cycle associated with a(n) has length A226625(n) and its largest element is A226624(n).
