Help, Grasshopper Hexagon Panel to Triangle Panel

Hello. I am new to Grasshopper.
I need help for two things.

First, I am trying to split hexagon panel into triangle panels, while the center point is slightly higher.
like this

And then, with the splited triangles, I would like to offset them 3mm, scaling a little bit down(0.7) and make surface between the original one and the offset triangles.

I appreciate your help. Thank you.
