Why are there only 3 diminished chords?

Because an octave is 12 semitones, stacking further minor 3rd above the top note of a diminished chord just repeats the same existing notes (D → F → A♭ → B → D → F → A♭ → B → D → etc.). ... This means there are only 3 unique diminished chords: Cdim7 = E♭dim7 = G♭dim7 = Adim7.
