 (すべてのフィールドは基本的に 32 bits.)

List :
 | tag 17  | length m | obj[0] | ... | obj[m-1] |
 (List を以下 [obj[0], ..., obj[m-1]] と書く.)

DMS :
 | tag 23  |

Coefficients:
 32 bit coefficients :
   | tag 21 | int |
 ZZ (GMP integer) :
   | tag 20 | {internal expression of GMP integer} |

Monomial:
 Monomial32 :
   | tag 19 | number of variables n | 
   | exponent[0] | ... | expoent[n-1] | {Coefficients} |
 ZeroMonomial :
   | tag 22 |



Polynomial:
 PolynomialByList :
    {Monomial32}  
   or
    [{DMS}, {RingDefinition}, {Polynomial}, ... , {Polynomial}]

RingDefinition:
  | tag 24 | 
  | tag 17 | length m |   (LIST)
   | INT32 number of variables |                  <m=0>
   | INT32 characteristic |or| RingDefinition |   <m=1>
   | LIST  name of variables |   (optional)       <m=2>
   | LIST  weight vector     |   (optional)       <m=3>

Example: Z/11Z [x,y]
 3 x^2 y + 1   ===> | 17(11) | 4(4) | {DMS}     |{RingDef}| {3 x^2 y} | {1} |
                    | 17(11) | 4(4) | 24(18)    |{RingDef}| {3 x^2 y} | {1} |
                               The length is four {DMS}, {RingDef}, 3x2y, 1.
