How to create a Multi-Network subsite?

Question

I've enabled Wordpress Multisite (subdomains) on www.example.com and created a subsite @ s.example.com, and then installed/enabled WP Multi-Network.

I've created a new network @ s.example.com.

How do I create a subsite in that network, e.g. s.example.com/subsite?

s.example.com/wp-admin/network redirects to www.example.com/wp-admin/network.

If I create a new site @ www.example.com/wp-admin/network/sites.php, I can't make it a subdomain or subdirectory of s.example.com.

Help appreciated.

It is just like @Ravi says, you can't create a multisite within a multisite environment. s.example.com is a multisite website, you can't split that multisite site into multiple other sites. Need to have 2 separate installs.
