Presentation

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

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

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