This is a semi-ordered 3-figure code of ten pages. When the book is opened, two pages show at a time this picture shows page 1. At the bottom of the right side page, the letters beginning the words of each opening are found. Pages 1 and 2 contain words commencing with the letters S, V, or M; pages 3 and 4 contains words commencing with N, T, Y, P, and Sh, and so on. Apart from this, the code is ordered, and this indicates the page as the first figure of a group, then row and finally column (CCCP, or SSSR in Latin rendering would encode as 119 , for example), but other orders of reading are possible.
