Presentation

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

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

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