%N Decimal expansion of first Chandrasekhar's nearest neighbor constant.

%C When n pointlike particles are distributed uniformly randomly in a unit volume, the mean distance between any of them and its nearest neighbor is c/n^(1/3).

%C For the most probable distance, see A213055.

%C Named after the Indian-American astrophysicist Subrahmanyan Chandrasekhar (1910-1995). - _Amiram Eldar_, Jun 27 2021
