Presentation

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

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

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