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