Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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