# Using `SimplicalComplex` on a set of sets

Say I have something like this:

```
[{{1,2},{2,3}} , {{1,2},{3,4}}]
```

So I have a list of sets consisting of subsets of $1,2,...,n\space$ (in general the lists I am interested in are longer). I get these by using `Subset(X,n)`

. Now I want to look at the simplicial complex with facets `{1,2},{2,3}`

and then the simplical complex with facets `{1,3},{3,6}`

and so on.

Now the `SimplicialComplex`

command only works for lists like so:

```
SimplicialComplex([[0,1], [1,2], [0,2]])
```

See here for more info on finite simplical complexes in sage.

My question is: what is the best way to go from my set of sets to a list of lists?

More generally what is the best way to deal the fact that most enumerative combinatorics I can do in sage gives me sets but for `SimplicialComplex`

I need lists?
