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