It  is quite difficult to write a specific solution to this great
adventure,  but  I have listed things to RECORD in each decade. I have
also  listed where the persons are in complex on the first day, so you
know where to find them if you have any questions to them (you can ask
Perelman  about a lot of people and things eg. plan, Perelman, Esther,
my name, Randu, Vera)
