It seems that groups are not cached when created. So if I create a same group twice, it will return two unequal objects.
```julia
julia> G = abelian_group(10)
Z/10
julia> G1 = abelian_group(10…

We should add a Group interface to the docs. Actually, we should add a general AbstractAlgebra object interface, since it seems like some things have to exist for every AbstractAlgebra object, regardl…

### What is the issue?
In a relatively simple prompt, one of the Phi models went off track and ranted for several thousand words. After, all future responses produced (mostly) garbage output, even in…

Initial implementation of Lie algebras in sage.
This will contain the following:
- Free Lie algebras
* Hall basis
* Lyndon basis
- Abelian Lie algebras
- Lie algebras from an associative algeb…

while I was (am) very happy to have found this function, I always thought an inner product combines sub-objects only? This sees to me an out product with maps (which is why I am happy)

I would like to use the commutative=False argument to symbols to make sure
my expressions aren't arbitrarily re-arranged. But in the case of boolean expressions,
I get some un-anticipated behavior.…

There's a construction called `Spec` which eats a commutative ring `R` and spits out a topological space `Spec R`. To a mathematician it is trivially true that if we have an isomorphism `f : R -> S` t…

We should find an existing library for this

We have a bunch of database for various objects in Oscar. At the very least, various group libraries:
- small groups
- transitive groups
- primitive groups
- perfect groups
But certainly we hav…

For example, is there any way to use CAP_project or homalg to actually compute, say, the Schur multiplier $M(G) = H_2(G, Z)$ of a finite permutation group, or $H^2(G, Z)$ resp. $H^2(G, C^*)$?
