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).

Cf. A226610, A226627, A226632, A226689.
