Presentation

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

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

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