Presentation

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

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

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