Presentation

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

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

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