shall be clothed with scarlet, and have a chain
of gold about his neck, and shall be the third
ruler in the kingdom. then came in all the king's
wise men but they could not read the writing,

troubled, and his countenance was changed in him,

Othello Neutron Equator Trajan
L'Albatros Charles Baudelaire (Les fleurs du
mal) Souven
t pour s'amuser les hommes d'equipage prennent
des albatros vastes oiseaux des mers qui suivent
indolents compagnons de voyage le navire glissant
sur les gouffres amers. A peine sle sont ils
deposes sur les planches que ces rois de l'azur
maladroits et honteux laissent piteusement leurs
grandes ailes blanches comme des avirons trainer
a cote d'eux. Ce voyageur aile comme il est
gauche et veule lui naguere si beau, qu'il est
comique et laid. L'uan agace son bec avec un
brûle gueule, l'autre mime en boitant l'infirme
qui volait le poete est semblable au prince des
nuees qui hante la tempète et se rit de
l'archer baudelaire exile sur le sol au milieu
des huées. Le mot pour l'étage quatre est
Trajan. Ses ailes de géant l'empêchent de
marcher.
Le mot pour l'étage quatre est Trajan.

Stage 6 - Solution
Othello Neutron Equator Trajan Illiad Molybden
um
This stage is number six and it is a playfair
cipher. The following stage is number seven
within the context of this competition and it
is encrypted according to an ADFGVX type cipher.
When you attempt to cryptanalyse stage seven you
will see that it is more complicated than a
straight forward ADFGVX cipher. Unfortunately I
can not give you any more clues. In terms of
this stage the shibboleth that you should take
note of is molybdenum. You will probably have
noticed by now that each stage is in a different
cipher and is usually in an appropriate language.
So the Vigenere stage was in French and this
playfair stage is in English. If the pattern
persists then the next stage will be in German.
But does the pattern persist?

Othello Neutron Equator Trajan Illiad Molybden
um
Pierre de Fermat wurde am 20.August 1601 in der
sudwestfranzoischen Stadt Beaumont de Lomagne
geboren. Der Vater Dominique Fermat war
ein wohlhabender Lederhandler und so kam Fermat
in den Genuss einer einer vorzuglichen
Schulbildung im Franziskanerkloster Grandselve
der sich ein Studium an der Universitat von
Toulouse anschloss. Ob sich Fermat schon als
junger Mann in der Mathematik besonders
hervorgetan hat ist ltsnipgt zahlten. ENDE. Das
gesuchte Wort ist Edison. ENDE. Der naechste
Teilnd der Umkehrwalze der Maschine. Es ist
dennoch zu beachten dass das Walzenlage falsch
wiedergegeben ist. Eigentlich sollen Walze 1 und
Walze 2 gegeneinander ausgetauscht werden.
Die urspruengliche Walzestellung und Ringstellung
und Steckerverbindungenstellung sind unbekannt.
