Here is the site:
They consider monotonic or 1 note scales which are just scales of octaves to be ditonic
They consider ditonic or 2 note scales to be tritonic scales
They consider tritonic scales to be tetratonic scales
they consider tetratonic to be pentatonic
and so on all they way up to considering chromatic or 12 note scales to be 13 note scales which are impossible on the piano unless you have a piano that plays quarter tones which do exist but are very expensive.
That is all because they consider the octave note as being different from the starting note when it isn't.
So If you ever go to this site and you see octatonic, use your common sense and the notes to tell that it is actually heptatonic. and do that same things for every kind of scale on that site.
