Norwood %J Mathematics %D 2009 %I arXiv %X It is shown that a finite group in which more than 3/4 of the elements are involutions must be an elementary abelian 2-group. A group in which exactly 3/4 of the elements are involutions is characterized as the direct product of the dihedral group of order 8 with an elementary abelian 2-group. %U http://arxiv.org/abs/0911.1154v1
