This is a compliation of the repeating symbols that appear at least twice in AA-073Ah, also known as the Book of Ioxotot
or the Theurang codex. It was made by hand from photographs taken of the original plates and later verified by a computer analysis. Some symbols predicted by the symmetry hypothesis do appear in the book, but only once. It has been demonstrated that the non-repeating symbols are with two exceptions found only on plates that contain a name or term that appears to have no translation. For the time being access to non-repeating symbols is restricted to Blue level operatives or higher.
