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