Presentation

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

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

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