Presentation

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

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

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