Presentation

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

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

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