A strict statistics of self avoiding random walks in $d$-dimensional discrete (lattice) and continuous space is proposed. Asymptotic analytical expressions for the distribution and distribution density of corresponding random values characterizing a conformational state of polymer chain have been obtained and their quantitative estimation has been given. It is shown that conformation of polymer chain possesses a structure of spherical or, more commonly, of elliptical shell diffusely blurred both outside and inside the polymer coil, which nucleus is statistically void and has a radius of about half of Flory radius. Statistics of self-avoiding walks describes completely an effect of excluded volume and meets the terms of Flory method in Pietronero's concepti.

Key words: Flory method, statistics, self-intersection, polymer chain, random walks, lattice, fatigue function, conformation
