Presentation

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

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

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