Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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