Can we connect 4G Core (NSA) to 5G Core (SA)?

Hi All.

Does 5G deployment 3x support SA?
3x- means Core is 4G.

In other words: Can we connect 4G Core (NSA) to 5G Core (SA)?
Or interworking of NSA and SA?

3x is for ENDC NSA (Lte + NR radio and 5G Core).

There is other option in NSA deployment where NR + LTE with 4G Core which is option 8.

Also for SA it has to be one radio and one Core, so we can have NR radio + LTE Core (option 6).

N26 interface connects 4G core to 5G core
