Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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