Presentation

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

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

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