Additional Information
Frederik Gijsbert van Dedem uses a nomenclature, mainly consisting of 3- and 4-digit codegroups, not unlike the code, used by him in 1809. This code was in use for for over 30 years and well known to S.E. Croiset, who probably wrote his solution-now lost- on a separate sheet.
