Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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