Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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