EXAMPLE

The irregular array starts:

(k=1)  1;

(k=5)  1, 3, 3, 17, 17;

(k=7)  2;

(k=11) 2, 8;

a(2)=1 is the number of odd elements in the 3x+5 cycle {1,4,2} associated with A226607(2)=1.

CROSSREFS

Row n begins with a(A226612(n)) and has length A226613(n).

The cycle associated with a(n) has length A226609(n) and its largest element is A226608(n).

Cf. A226611, A226626.
