Presentation

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

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

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