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