Presentation

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

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

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