Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 28 points:

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