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