This may help:
- How is a multilayer PCB made? https://www.fedevel.com/welldoneblog...r-pcb-is-made/
- PCB Manufacturing – Important facts you should know https://www.fedevel.com/welldoneblog...u-should-know/

I believe what you mean by 2-4-2 is drilling (uVIAs from L1 to L3, then buried via L3 to L6 and then uVIA L6 to L8).
