Presentation

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

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

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