Presentation

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

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

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