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