Presentation

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

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

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