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