Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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