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