摘要翻译：
用形式术语讨论了遗传密码的结构。代码的一个矩形表（“代码矩阵”），它的性质显示了它的算术内容，并用几个符号标记了信息符号。新的参数用于分析编码矩阵，编码产物和编码元素的序列号，按分子质量排序。发现两类氨基酰基tRNA合成酶所对应的氨基酸序列在结构上具有相似性。代码矩阵显示了如何组织所谓的第二遗传密码。其它参数支持矩阵的对称性；它也是根据最简单的柏拉图实体四面体的结构来构造遗传密码的三维模型的基础。这种不寻常的遗传密码结构的原因尚不清楚。

英文摘要：
The structure of the genetic code is discussed in formal terms. A rectangular table of the code ("the code matrix"), whose properties reveal its arithmetical content tagged with the information symbols in several notations. New parameters used to analyze of the code matrix, the serial numbers of the encoded products and coding elements, ordered by molecular mass. The structural similarity of the amino acid sequences corresponding to two aminoacyl tRNA synthetases classes is found. The code matrix shows how can be organized the so-called second genetic code. The symmetrical pattern of the matrix is supported with the other parameters; it also serves as a basis to construct a 3D model of the genetic code which follows the structure of the simplest Plato solid, tetrahedron. The reasons for this unusual structure of the genetic code remains unclear.
