Presentation

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

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

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