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