How many aggregator nodes in free version

I want to try free cluster and got a question.

According to FAQ
#### What is included in the free version of SingleStore?

SingleStore offers a free tier for clusters up to 4 nodes (not including Aggregator nodes) and up to 128 GB Memory Capacity. Unlike other database providers, the freely downloadable version of SingleStore is full-featured and includes all the performance, security, and capabilities available in any version of our database. There are no time or deployment restrictions.

Does that mean that I can run Master Aggregator + Aggregator + 4 Leaves?

Yes, you can do that.
