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