Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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