N - nucleons and leptons. NH - nucleons, hyperons, and leptons. Exotic states of hadronic matter are indicated explicitly. Maximum allowable mass for non-rotating stars, $M_{\rm max}^{\rm stat}$, and the circumferential radius of non-rotating stars of $1.4~M_\odot$, R1.4, are given in last two columns, respectively.
