Presentation

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

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

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