Presentation

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

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

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