Factor Groups, Permutation Representations, Finite Point Groups,ns. This allowed a rough evaluation of evolutionary relatedness between the various groups of protists analyzed. The results are discussed within the framework of a number of published phyllogenies and shown to be in striking agreement with some of the schemes.Obstacle 发表于 2025-3-23 19:40:49
