Presentation

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

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

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