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