Presentation

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

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

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