I have searched the internet for how to form the following words, but have been unable to find an authoritative source. They are obviously formed with latinate prefixes, but if you look at the lists here, the sandhi/morphotactics are not straightforward.
With regard to words describing equally divided parts of a plane, how are the following words formed, and do I even have them right?
4 - quadrant 5 - quintant 6 - sextant 7 - septant ??? 8 - octant 9 - nonant 10 - decant/decimant ??? 16 - sedecimant ??? 64 - sexagesim quadrant ??? 100 - centant/centasimant ??? 400 - quadringentant/quadringentesimant ???
