Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 4 generators on 28 points:

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