For those who like arithmetic problems: calculating the environmental meaning of a law … ;-)

Recently somebody, i.e. a surely historically meaningful figure passed away – his name at birth reads as follows: Seine Kaiserliche und Königliche Hoheit Franz Joseph Otto Robert Maria Anton Karl Max Heinrich Sixtus Xaver Felix Renatus Ludwig Gaetan Pius Ignatius, Kaiserlicher Prinz, Erzherzog von Österreich, Königlicher Prinz von Ungarn (His imperial and Royal Highness Franz Joseph Otto Robert Maria Anton Karl Max Heinrich Sixtus Xaver Felix Renatus Ludwig Gaetan Pius Ignatius, imperial prince, archduke of Austria, royal prince of Hungary). There is some evidence from Historical Research by Andrea Maria Dusl, an Austrian multiple expert, writing for Falter, giving evidence to the fact that the actual and final name of this person had been Dr. Franz Matfried. This subsequently follows from the following: the Austrian ‘law abolishing nobility’ did not allow further use of any titles and reference like this. Also: The Habsburigan root actually died off in 1740; Lorraine had been governed by the house of Châtenois, bearing since 795 the family name ‘Die Matfriede’, thus the name Dr. Franz Matfried. [Franz recently spoiled a little bit my lunch here in town – well, his last visit in town (i.e. currently Munich) meant that I had to make a change in my lunch plan as if the world would not be turbulent enough without such things]. Anyway, the arithmetic problem now: The name at birth (German version) has 225 characters (incl. spaces), the final name has 18. Calculate the meaning of the environmental of the Austrian law abolishing nobility under the condition that the person in question would have signed just two letters per day during his adult time.
