Presentation

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

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

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