Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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