Presentation

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

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

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