Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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