Presentation

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

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

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