% Version  : [Mat16] axioms : Especial.
% English  : Answer the following questions.  (1) When A=(begin{matrix} 2 & 4 
%            -1 & -1end{matrix}) and E=(begin{matrix} 1 & 0 0 & 
%            1end{matrix}), find A^6+2 A^4+2 A^3+2 A^2+2 A+3 E.  (2) Consider 
%            the quadrangular pyramid OABCD whose base is the quadrilateral 
%            ABCD. The point P is at the vertex O at the time of 0, and moves 
%            to any of the 5 vertices of the quadrangular pyramid every 1 
%            second according to the following rule: Rule: Move to any of the 
%            vertices connected to the vertex where the point P exists via 
%            one side with the same probability. Find the probability that 
%            the point P is at the vertex O after n seconds.
