Presentation

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

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

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