Presentation

minimal degree	μ(G) = 23
transitive degree	μ_t(G) = 192

A minimal faithful permutation representation — 3 generators on 23 points:

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

Polycyclic presentation:

2^9,3|a^2=d,b^2=e,c^2=dh,g^2=i,b^a=bf,c^b=cfgi,d^b=di,e^a=ei,f^a=fi,f^b=fi,f^c=fh,g^a=gh,g^b=gi,g^c=gh,g^f=gi,h^b=hi,j^c=j^2
