Abstract:

We investigate faithful representations of Alt(n) as automorphisms of a connected group G of finite Morley rank. We target a lower bound of n on the rank of such a nonsolvable G, and our main result achieves this in the case when G is without involutions. In the course of our analysis, we also prove a corresponding bound for solvable G by leveraging recent results on the abelian case. We conclude with an application towards establishing natural limits to the degree of generic transitivity for permutation groups of finite Morley rank.
