Note: fix typos 
changed:
-AldorCombinat can also count the number of isomorphism types of structues.
-That is encoded in the isomorphim type series.
AldorCombinat can also count the number of isomorphism types of structures.
That is encoded in the isomorphism type series.

Test species in axiom/FriCAS?.

Let's count how many structures of a certain size exist. This is encoded in the generating series. Note that this is an exponential generating series. 

axiom
es: ExponentialGeneratingSeries := generatingSeries()$X;
Type: ExponentialGeneratingSeries?
axiom

Type: List ACFraction? ACInteger?
axiom
[count(es, i)       for i in 0..10]

Type: List ACInteger?

AldorCombinat? can also count the number of isomorphism types of structures. That is encoded in the isomorphism type series. 

axiom
os: OrdinaryGeneratingSeries := isomorphismTypeGeneratingSeries()$X;
Type: OrdinaryGeneratingSeries?
axiom
[coefficient(os, i) for i in 0..10]

The output of the next command apparently causes a "Proxy Error" on the mathaction server. This can be avoided by changing the output from LaTeX? to ASCII mode:
