Presentation

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

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

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

Polycyclic presentation:

2^9,3|b^2=dfi,c^2=h,f^2=i,g^2=i,b^a=bd,c^a=cde,c^b=cdfg,d^b=dh,d^c=dhi,e^b=eh,e^c=ehi,f^a=fh,f^b=fh,f^c=fi,f^d=fi,f^e=fi,g^b=gh,g^c=ghi,g^f=gi,h^b=hi,j^c=j^2
