Presentation

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

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

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