Presentation

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

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

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