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