Presentation

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

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

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