Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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