\par Simultaneous resolution of the nonzero torsion equations and the matrix$

equation USD J^2 = -I . USD$

First, one gets from  equation USD35|2USD :$

\\ USD xi(2,5):=0USD$

\\ Then one gets from  equation USD45|1USD :$

\\ USD xi(1,5):=0USD$

\\ and from  equation USD46|2USD :$

\\ USD xi(2,6):=0USD$

\\ Then one gets from  equation USD14|2USD :$

\\ USD xi(2,4):=0USD$

\\ Then one gets from  equation USD15|4USD :$

\\ USD xi(4,5):=0USD$

\\ Then one gets from  equation USD25|3USD :$

\\ USD xi(3,5):=0USD$

\par With these values, \textit{Reduce} computes again all equations.$

Then the 5x5 entry in  USD J**2 USD  is $

USD  {J**2}^5_5=xi(5,5)**2 + xi(6,5)*xi(5,6);USD\\$

Hence USD xi(6,5)xi(5,6)\neq 0 USD$

and USD xi(5,6) =(-1-xi(5,5)**2)/xi(6,5). USD$

\\ USD xi(5,6):= - (xi(5,5)**2 + 1)/xi(6,5)USD$

Moreover, the 6x5 entry in  USD J**2 USD  is $

USD  (xi(6,6) + xi(5,5))*xi(6,5);USD hence\\$

\\ USD xi(6,6):= - xi(5,5)USD$

Moreover, the 4x5 entry in  USD J**2 USD  is $

USD  xi(6,5)*xi(4,6);USD hence\\$

\\ USD xi(4,6):=0USD$

and the 3x5 entry in  USD J**2 USD  is $

USD  xi(6,5)*xi(3,6);USD hence\\$

\\ USD xi(3,6):=0USD$

and the 1x5 entry in  USD J**2 USD  is $

USD  xi(6,5)*xi(1,6);USD hence\\$

\\ USD xi(1,6):=0USD$

\\ Then one gets from  equation USD24|1USD :$

\\ USD xi(1,4):=0USD$

\par With these values, \textit{Reduce} computes again all equations.$

Then the 4x4 entry in  USD J**2 USD  is $

USD  {J**2}^4_4=xi(4,4)**2 + xi(4,3)*xi(3,4);USD\\$

Hence USD xi(4,3)xi(3,4)\neq 0 USD$

and USD xi(3,4) =(-1-xi(4,4)**2)/xi(4,3). USD$

\\ USD xi(3,4):= - (xi(4,4)**2 + 1)/xi(4,3)USD$

Moreover, the 3x4 entry in  USD J**2 USD  is $

USD  (xi(4,4) + xi(3,3))*xi(3,4);USD hence\\$

\\ USD xi(4,4):= - xi(3,3)USD$

Moreover, the 1x4 entry in  USD J**2 USD  is $

USD  xi(3,4)*xi(1,3);USD hence\\$

\\ USD xi(1,3):=0USD$

\\ Then one gets from  equation USD13|3USD :$

\\ USD xi(2,3):=0USD$

\par With these values, \textit{Reduce} computes again all equations.$

Then the 1x1 entry in  USD J**2 USD  is $

USD  {J**2}^1_1=xi(1,1)**2 + xi(2,1)*xi(1,2);USD\\$

Hence USD xi(2,1)xi(1,2)\neq 0 USD$

and USD xi(1,2) =(-1-xi(1,1)**2)/xi(2,1). USD$

\\ USD xi(1,2):= - (xi(1,1)**2 + 1)/xi(2,1)USD$

Moreover, the 1x2 entry in  USD J**2 USD  is $

USD  (xi(2,2) + xi(1,1))*xi(1,2);USD hence\\$

\\ USD xi(2,2):= - xi(1,1)USD$

Then the 4x1 entry in  USD J**2 USD  gives $

\\ USD xi(4,2):=( - xi(4,3)*xi(3,1) + xi(4,1)*xi(3,3) - xi(4,1)*xi(1,1))/xi(2,1)
USD$

\par With these values, \textit{Reduce} computes again all equations.$

Then the 6x1 entry in  USD J**2 USD  gives $

\\ USD xi(5,1):=( - xi(6,4)*xi(4,1) - xi(6,3)*xi(3,1) - xi(6,2)*xi(2,1) + xi(6,1
)*xi(5,5) - xi(6,1)*xi(1,1))/xi(6,5)USD$

Then one gets from  equation USD14|6USD :$

\\ USD xi(1,1):=(xi(6,5)*xi(3,3) + xi(5,5)*xi(2,1) - xi(3,3)*xi(2,1))/xi(6,5)USD

\par With these values, \textit{Reduce} computes again all equations.$

\\ Then,   equation USD13|6USD reads :$

 USD{1,3}|6\\xi(6,5)*xi(4,3) + xi(6,5)*xi(2,1) - xi(4,3)*xi(2,1) =0 USD\\$

Hence USD xi(4,3) +xi(2,1) \neq 0USD and $

\\ USD xi(6,5):=(xi(4,3)*xi(2,1))/(xi(4,3) + xi(2,1))USD$

Then the 4x2 entry in  USD J**2 USD  gives $
