Why does the f orbital start at 4?

Hi!
When we look at the four quantum numbers, it can help explain why only n=4 and higher can support an f-subshell. For whatever n is, l (angular momentum number) can be any integer up to n-1. For n=4, l can be at most 3. L=3 corresponds to an f-subshell. Any principal quantum number below 4 could thus not support an f-subshell.
Hope this helps!
