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