EXAMPLE
The irregular array starts:
(k=1) 1, 7, 91;
(k=11) 29;
(k=17) 179, 143;
(k=19) 505;
a(4)=29 is the largest element 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 A226626(n) odd elements.
Sequence in context: A243699 A007820 A306137 * A266236 A123694 A319978
