Presentation

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

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

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