Presentation

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

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

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