Presentation

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

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

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