Presentation

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

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

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