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