Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 24 points:

(1,2,4,7)(3,5,8,6)(9,10)(11,17)(12,20)(13,16)(14,18)(15,21)(19,24)(22,23);(2,5)(3,8)(6,7)(12,21)(14,23)(15,20)(18,22);(9,11,13,19)(10,14,16,23)(12,22,21,18)(15,24,20,17);(2,5)(3,8)(6,7)

Polycyclic presentation:

2^9|a^2=h,c^2=i,e^2=h,f^2=i,b^a=be,c^a=cf,d^a=de,e^a=eh,f^a=fi,g^a=gi,c^b=cg,e^b=eh,f^b=fi,f^c=fi,e^d=eh
