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