Sequences
A124734 Triangle read by rows, in which row
sorts the
compositions of
by increasing length, and then by increasing
lexicographic order. Similar to the
“Abramowitz and Stegun” ordering of the partitions,
A036036.
For example, the fifth row reads
- (5),
- (1, 4), (2, 3), (3, 2), (4, 1),
- (1, 1, 3), (1, 2, 2), (1, 3, 1), (2, 1, 2), (2, 2, 1), (3, 1, 1),
- (1, 1, 1, 2), (1, 1, 2, 1), (1, 2, 1, 1), (2, 1, 1, 1),
- (1, 1, 1, 1, 1).
A296774 Triangle read by rows, in which row
sorts the
compositions of
by increasing length, and then by decreasing
lexicographic order.
For example, the fifth row reads
- (5),
- (4, 1), (3, 2), (2, 3), (1, 4),
- (3, 1, 1), (2, 2, 1), (2, 1, 2), (1, 3, 1), (1, 2, 2), (1, 1, 3),
- (2, 1, 1, 1), (1, 2, 1, 1), (1, 1, 2, 1), (1, 1, 1, 2),
- (1, 1, 1, 1, 1).

colexicographic order.
For example, the fifth row reads
- (5),
- (4, 1), (3, 2), (2, 3), (1, 4),
- (3, 1, 1), (2, 2, 1), (1, 3, 1), (2, 1, 2), (1, 2, 2), (1, 1, 3),

sorts the
compositions of
by increasing length, and then by decreasing
colexicographic order.
For example, the fifth row reads
- (5),
- (1, 4), (2, 3), (3, 2), (4, 1),

Notes
- ↑ We should consider having the empty sum here, the leading zeros not being normally represented (we put the leading zero for zero only to avoid an empty representation for zero, which would not be convenient).
