Presentation

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

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

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