Presentation

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

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

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