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
