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