Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

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