Presentation

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

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

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