Presentation

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

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

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