Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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