Presentation

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

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

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