Presentation

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

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

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

Polycyclic presentation:

2^9|a^2=f,b^2=g,c^2=f,f^2=h,g^2=i,b^a=be,d^a=dh,c^b=ch
