Presentation

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

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

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