Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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