 material:

   [  e_11  e_12  e_13  |
   |                    |
   |  e_21  e_22  e_23  |

   |  e_31  e_32  e_33  ]

So, for example, let us suppose that we have the small universe {A, B, C},
and the 2-adic relation m = &quot;mover of&quot; that is represented by this matrix:

   m  =

   [  m_AA (A:A)   m_AB (A:B)   m_AC (A:C)  |
   |                                        |
   |  m_BA (B:A)   m_BB (B:B)   m_BC (B:C)  |
   |                                        |
   |  m_CA (C:A
