Presentation

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

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

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