Presentation

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

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

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