This tables contain data of several types - polynomial coefficients,
some constants, lookup-tables.

Values was calculated with Maple, Mathematica and Sollya.

What is requirements for data representation? Lets determine how
values will be represented here.

We can add some comments but regeneration of this tables is not supported.
