Presentation

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

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

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