Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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