Presentation

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

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

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

Polycyclic presentation:

2^9,3|a^2=f,b^2=efh,c^2=dfgi,g^2=i,b^a=be,c^a=cd,c^b=cfgi,d^a=dh,e^b=ei,e^c=eh,e^d=ei,f^c=fh,f^d=fi,g^a=gh,g^c=gh,g^d=gi,g^e=gi,g^f=gi,h^a=hi,h^b=hi,j^b=j^2
