Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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