Presentation

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

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

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