Presentation

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

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

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