Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 4 generators on 28 points:

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