Each small inner table groups the inversions (rotations) of a single chord class. In every row, the left cell names the chord by listing its intervals above the root note of that inversion, and the right cell gives the same information as a set of degrees.

	The first row of each inner table is a distinguished representative: among all inversions of the chord, it is the one whose pitch classes, when ordered along the 17-EDO circle of fifths (0–10–3–13–6–16–9–2–12–5–15–8–1–11–4–14–7), form the lexicographically smallest sequence. The remaining rows list the other inversions of the same chord, in the order obtained by successive rotations.
