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