155. Deduction of ce x e 2 C 600 by composition of ce 2 C eoo and 

 ce \ ^600 an< ^ °* e i e 2 ^600 ^.y composition of cej e 2 C 600 and C 600 . 



In the addition . applied to find a coordinate-symbol of ce x e 2 C 600 

 we replace the vertex of ce 1 (' &K) by the two vertices of 6' 600 from 

 which it can be deduced, and after that we again add the coord- 

 inates of each of these two vertices successively to obtain the coord- 

 inate-symbols of e x e 2 C 600 .
