Sorry for this question, I know it's a very basic one, but can't find proper answer to it.
There is no problem with for example NACA 63-415,
6 - series number
3 (30%)- laminar boundary layer from the leading edge
4 - lift coefficient
15 - thickness in percentage of chordlength
But I have some doubts about for example this one NACA 65(2)-415 what means that 2 in the bracket? Or 65(215) -114, 65(sub)4-221, etc
