Abstract: A table contains codes for consecutive decimally numbered pages and pages whose numbers contain hexadecimal digits. Codes for all the pages having decimal units numbers are arranged in rows and columns such that a column contains codes for pages having a same units number, and codes for pages having a same tens number (whether decimal or hexadecimal) are in the same row. Codes for pages having a hexadecimal units number are arranged in a continuation of the rows and columns, hexadecimal units being arranged in the columns under the corresponding decimal units.
