Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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