Abstract

We prove that the highest rank of a string C-group constructed from an alternating group A_n is 3 if n=5, 4 if n=9, 5 if n=10, 6 if n=11, and ⌊(n−1)/2⌋ if n⩾12. Moreover, if n=3,4,6,7, or 8, the group A_n is not a string C-group. This solves a conjecture made by the last three authors in 2012.
