Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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