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