Weirdness
- sage.combinat.word is not imported by default
- word.symmetric_group_action_on_values does not naturally belong in word
- word.standard should be called word.standardization
- word.charge returns the cocharge
CombinatorialAlgebra has no useful documentation
CombinatorialClass has no documentation
It would be nice for CombinatorialObject to have a method 'indices' which returns a list of the index of *every* occurrence of x
Compositions has no option for allowing '0' parts (which are often useful) (IntegerVectors does this. There should be a pointer.)
- Composition.conjugate() is not explained
- Composition.descents() is not explained
- Composition.major_index() doc-string says it is the sum of the descents. This is not true for the given example.
- Composition.refinement() is not explained
SignedCompositions has no corresponding class SignedComposition
DyckWords? does not define Dyck words
DyckWord.b_statistic() is not explained
DyckWord.height() is not explained
DyckWord.peaks() is not explained
DyckWord.to_noncrossing_partition() could use a better reference
DyckWord.to_tableau is not explained
DyckWord.to_* for * in {ordered_tree, triangulation} is not implemented. Warning: Implementing bijections between Catalan objects can be a never-ending task.
IntegerVectors has no corresponding class IntegerVector
WeightedIntegerVectors has no corresponding class WeightedIntegerVector
