Description

Currently the following breaks: 

sage: P = Partitions(5, max_length=4)
sage: loads(dumps(P))

since PartitionOptions does not pickle, hence the IntegerListsLex, which takes it as an (optional) input, does not.

The proposed solution is two-fold:

  • Add a class for partitions that inherit from IntegerListsLex (or use it as an iterator).
  • Add a warning when using the global_options parameter that the resulting class might not pickle.

Here's also a discussion on sage-combinat-devel:

I'm also going to add parent classes for k-regular partitions.

comment:16 Changed 4 years ago by kdilks

So far only noticing very minor issues.

  • In the definition of being \ell-regular, it should mention that m_i is the multiplicity of i in the partition. The first time I looked at this, I thought that m_i was maybe referring to the part sizes. In the source code you can just search for 'm_i' to see what it means, but in the HTML doc 'm_i' is always going to be Tex'd and harder to search for. Also, character_polynomial() doc used a_i to refer to the multiplicity of i in a permutation alpha, so maybe that should be changed to m_i to be consistent.
  • Does the code ever check that \ell is an integer, and preferably a nonnegative one?
