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