Presentation

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

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

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