Presentation

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

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

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

Polycyclic presentation:

2^9,3|b^2=fgi,d^2=i,g^2=i,b^a=bf,c^a=ce,c^b=cfg,d^b=dh,d^c=dhi,f^b=fh,f^c=fhi,g^a=gh,g^b=gh,g^c=ghi,g^d=gi,g^f=gi,h^b=hi,j^c=j^2
