Presentation

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

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

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