Presentation

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

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

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