Presentation

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

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

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