Presentation

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

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

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