Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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