EXAMPLE

The irregular array starts:

(k=1)  2;

(k=5)  3, 5, 5, 27, 27;

(k=7)  4;

(k=11) 6, 14;

a(2)=3 is the length of 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 A226610(n) odd elements of which A226608(n) is the largest.

Cf. A226611, A226625, A226670-A226672.
