A subset R of a finite group G is a square root of G if R2 = G. If R is a square root of G for which |R|2 = G, then R is referred to as a perfect square root of G. It can be shown using character theory that perfect square roots do not exist. The purpose of this paper is to work toward an elementary proof of this result.

Let G be a finite group of order n2. A perfect square root of G is a subset X of G such that |X| = n and X2 = G. Neither generalized dihedral groups nor groups of nilpotency class two have perfect square roots.

Let r be a rational in (0,1]. There exists a finite group G which is the direct product of at most four metacyclic groups and whose proportion of normal subgroups is r. An analogous result holds for three other measures of "Hamiltonianess".

Let G be a finite group and let WG denote the proportion of triples, (.x:, y , z) , i n G3 for which x yz , x zy, y x z, zx y , yzx , and z y x have the same order. The following results are established.
i) G is abelian if, and only if, WG = 1.
ii) WG can be arbitrarily close to 1.
iii) Additional estimates on WG
