Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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