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