How to implement a hierarchy of nodes linked to the hierarchy of admins?

Question

Hierarchical structures

Please tell me the way to implement the hierarchy of nodes combined with the hierarchy of administrators.
Level 1 administrator creates level 2 administrators, level 2 administrator creates level 3 administrators, and so on.
Also, each administrator has the ability to create his own group (only one), view only his BRANCH of nodes (up to the last level), edit the nodes of his group.
