Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(13,14,16,20,17,18,23,25)(15,19,22,26,21,24,27,28);(5,6,7,9,8,10,11,12)(14,18)(19,24)(20,25)(26,28);(1,2,3,4)(13,15)(14,19)(16,22)(17,21)(18,24)(20,26)(23,27)(25,28);(15,21)(19,24)(22,27)(26,28)

Polycyclic presentation:

2^9|a^2=e,b^2=f,c^2=g,e^2=h,f^2=i,b^a=bh,d^c=dh
