Presentation

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

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

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