Presentation

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

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

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