EXAMPLE

Table A140691 begins

1..2..4..8..16..32

..3..5..9..17..33

.....7.11..19..35

.......15..23..39

...........31..47

...............63

.................

........6..10..18

...........13..21

...............27

since each matching case, say x, is generated by the rule "2x+1",

only the even cases map to cyclic partitions; so the sequence begins

1..2..4..8..16..32

........6..10..18

...............12

...............14

CROSSREFS
