### Computer Algebra

Since MuPAD went commercial
I use
Axiom
for calculations.
Actually, the most useful fork of Axiom at the moment
(and perhaps for the next 30 years) is
FriCAS;
but see also OpenAxiom.

### Combinatorial Probability

Some time ago I started to write a package for combinatorial probability
theory in FriCAS.
It can handle computations with moments, cumulants and orthogonal polynomials
and is included in the FriCAS library since release 1.1.4.
Here is a short description
and example files
1 ,
2 ,
3 ,
4 .
Here is a source code
is annotated using
`noweb`
and typeset here.

In the future I plan to release packages for set partitions
and algebras which will allow to handle multivariate noncommutative probability as well.
