Presentation

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

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

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