Presentation

minimal degree	μ(G) = 23
transitive degree	μ_t(G) = 96

A minimal faithful permutation representation — 4 generators on 23 points:

(2,3)(5,7)(9,16)(15,17);(1,2,3)(5,7)(9,15)(10,19)(11,12)(14,22)(16,17)(18,23);(5,7)(8,10,11,20,13,19,12,21)(9,14,15,22,16,23,17,18);(4,5,6,7)(8,9,12,17,13,16,11,15)(10,18,21,23,19,22,20,14)

Polycyclic presentation:
