Presentation

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

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

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