Presentation

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

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

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

Polycyclic presentation:

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